joe's example is not  viable because Joe only looks at the people going to pizza pizza for lunch time. He could have gave them a survey so that he could save a lot of time.
Carla's is not viable as well because there would be people who don't have Facebook. Instead of that she could have made an google form (online survey).
Arun's example is definitely not viable and is bias because if he asks people who play soccer they will most likely pick soccer. He could of asked people who don't play sports and they'll give an unbiased answer.
Ariel's answer is viable. The part I think she could have done is only ask the grade eight after all it is their graduation.

# data[].attributes.body
1. Joe's example is not viable because he is only counting the people that go to pizza pizza at lunch while there are also other places students go at lunchtime. He also might have counted wrong people that are in grade 7/8 that he saw in pizza pizza. Instead of doing what he did, he should just go and give a survey to the grade 7/8 students which would be more easier and it would save him more time.
2. Carla's example is also not viable because not everyone has facebook. Some people have other social media apps other than facebook. What Carla should have done is make a poll and email it to all the grade7/8.

3.Arun's example is not a viable. what Arun did wrong is he asked the players on the soccer team what their favourite sport is, which is obviously soccer, and he only asks the soccer players who might not be in grade 7/8. What he should have done is create a survey and had it out to the grade 7/8 students to fill it out.

4. Ariel's example is viable. The only thing she did wrong is asking the whole school to fill the poll out. While it only for grades 7/8, so they are the only ones who need t fill it out.

Joe:
1. Joe is being completely bias or is just naturally oblivious. Joe's example is not a viable technique because he is *cough* *cough* stupid! Just kidding (not really). He is looking at one of the many lunch destinations students are attending, which makes his data very much wrong. Avoiding the fact that not all students enjoy the same food, Joe still decides to only stand outside of pizza pizza and count students (like the creep he is).
2. Instead of freezing his butt off by standing outside of Pizza Pizza he could easily ask students of the grade 8 & 7 class what lunch destination they enjoy to eat. He could also stand by a food court or in a plaza and write it down.

Arun:
1. Arun was dropped as child therefore he does think well, #PRAYFORHIM. His example is not viable! He asked his soccer team what their favorite sport is. OH jeez I wonder what their favorite sports are...SOCCER! Unless he planned all along for them to say "soccer," than I really don't know what to say but what an idiot! He is teammates are going to be bias because clearly they enjoy soccer, seeing how they are in a soccer team which is an extra curricular activity and it isn't mandatory to do.
2. Maybe...I don't know...ask the students in his class because if he goes to different sports teams they're most likely going to say that the sports teams they play in is they favorite sport.

Ariel:
1. Well we know who's the smartest at of these four. As viable as her answer is...why would she be asking her whole school to take the survey if it's for a graduation for the grade-eights only? The small children are not a part of the graduation and they we'll chose their favorite colours, completely ignoring what the grade 8's would want.
2. Ariel should stick with her original plan but instead of asking the whole school why not just ask the classes that are graduating, the grade eight classes.

Carla:
1.  Carla's technique is also not viable. First of all, not everyone has Facebook, the fact is that most 7's & 8's will use Instagram and Snapchat because we live in the generation where these two social medias are the most popular.
2. She can name different rock band and do polls which are an added feature on Instagram; it give you the percent of people that voted and it shows who voted for this. If she only has Facebook she can talk to both the clases to write down their favorite rock band. She can also create a survey on Microsoft forms and give the links to each class.

# data[].attributes.body
Card A: Joe's example is not a viable sample technique. He only surveys students entering Pizza Pizza, meaning all these students already likely prefer Pizza Pizza, making this technique unreliable. Instead Joe could stand in a mall or a cafeteria with many different eateries, and survey grade 7 and 8 students there. There would be a broader variation of choices, making it a better sample technique.

Card B: Carla's example is not a viable sample technique. She only surveying kids on Facebook. Not many kids use Facebook, and the ones that do, might not necessarily follow her. She could also get replies from others who are not in grade 7 or 8, or not in her school, which would mess with her data. Instead she could post her survey on a different social media site (ex. Instagram, Snapchat, etc.)

Card C: Arun's example is not a viable sample technique. He's only surveying kids on his soccer team, about their favorite school, and using that data to represent his whole school. The likelihood is that the players on the soccer team will prefer soccer to other sports, making this technique unreliable. Instead Arun could survey a couple students from each class, and not only from his soccer team.

Card D: Ariels' example is a viable sample teechnique. However, there is a flaw in her plan. As this is the grade 8 graduation, she only needs to survey the grade 8 classes, and shouldn't survey all the younger classes. To improve her method she should only send the poll to the grade 8 teachers to survey their classes.

# data[].attributes.body
1.
a) It is quite simple to find Joe's error. He is only surveying people who go to Pizza Pizza. This means that most of them would prefer pizza over other food items.
b) Joe can improve his sample by asking kids as they walk out of school, or he could make it easier for himself and create an online survey that he could email to everyone.

2.
a) Not many Grade 7's or 8's use Facebook, so the target audience will not get to participate. I actually checked the statistics and there is almost nobody under 18 who uses Facebook in Canada.
b) She could use Facebook along with other social media sites, such as Instagram, Twitter, etc.

3.
a) The problem here is that he is asking members of a soccer team, who(most likely)like to play soccer.
b) Arun could ask kids as they walk out of school, or he could make an online survey and spread it using social media.

4.
a) The problem is that most of the kids are not in Grade 8, so they probably don't care. They might want to make the Grade 8's angry by all choosing a colour like brown. Also, the younger kids may choose their favourite colour, and since the little kids outnumber the Grade 8's 10 to 1, you might end up with a graduation party with orange walls.
b) She could just survey Grade 8 classes, or she could make an online survey and email it to her classmates.

# data[].attributes.body
1. Joe’s technique is not viable. He only stands outside one lunch destination instead of watching over many. A way he can improve this technique is to stand infront  of the plaza and constantly watch who goes in what destination and write it down.
2. Carla’s method is not viable. A good reason why is not many kids nowadays use Facebook on a daily basis. Another reason why is not everyone is going to see that pole. Like said before, kids nowadays don’t use Facebook on a daily basis.so for her to but the pole there is not a smart move.
3. Is this really a question? NO it is not viable. If you think about realistically, going to a soccer team is the (sorry for saying this) a very stupid move. If you wanna make this method viable, go to every class and ask each student! It’s that simple.
4. It is not viable just like every other card. Going class to class isn’t smart as they aren’t gonna be at the graduation so they won’t really care. She should go to the grade 8 students and ask them what colours and ask them what their parents or guardian want.

# data[].attributes.body
1. I think that Joe's sample technique is not viable because if he only stands outside of pizza pizza to survey, then most of the kids who he surveyed will probably have pizza pizza as their favorite lunch destination. To solve this issue, Joe can go to pizza pizza, and have some of his friends go to other popular lunch destinations and then they each survey the kids at their spot.

2. Carla's technique is also not viable in my opinion because most intermediate students don't use Facebook. To solve this, Carla can post, " What is your favorite rock band" on multiple different social medias such as Instagram or Twitter.

3. Arun's sample technique is definitely not viable because if he only asks the soccer team, they will most likely all say their favorite sport is soccer. Instead Arun can ask his entire what their favorite sport is.

4. Ariel's sample technique is not viable viable because if she asks the entire school, all the little kids will chose colors like bright pink or blue, meanwhile those are not colors that appeal to most student.

# data[].attributes.body
1. no this isn't a reliable source because he surveys every other student that walks in, everyone that's walking in there is going to pizza pizza.
2. I think this would be a reliable source because she could find a good amount of people with an answer as to what their favourite rock band is however what if she has random people on her facebook the she wont get the certain people she needs to answer her survey
3.arun is only surveying the soccer team who most likely prefer soccer as their favourite sport.
b) arun can fix this technique by asking random people.
4.Ariel is asking the whole school for a grade 8 graduation ceremony which is obviously only for grade 8's.
b) she can only ask grade 8's what they want. Stupid Ariel *sigh

CARD A Joe is trying to find out the most popular lunch destination for students in grade 7 & 8 at his school. To do this, he decides to stand outside Pizza Pizza at lunchtime on Friday. He surveys every other student that walks into Pizza Pizza.

This is not a reliable source because he is standing outside a pizza shop so, everyone who enters the Pizza Pizza, obviously is going to choose pizza as their favorite food.

CARD C Arun wants to know the most popular sport for grade 7 & 8 students in his school. To do this, he decides to ask all the players on his soccer team what their favorite sport is.

1. What is wrong with Arun's technique?

Arun is asking soccer players, who clearly enjoy the sport, what their favorite sport is, so all the ansers he is going to recieve are going to be just soccer.

2. How could you improve it?

Go to different classrooms and ask what each students favorite sport is.

CARD B Carla is trying to decide what the favourite rock band is for grade 7 & 8 students at her school. To do this, she posts a note on Facebook and asks people to respond to her question: What is your favourite rock band?

This could potentially be a reliable source since many different people can answer, although depending on who her friends are on facebook she could get responses from older kids.

CARD D Ariel would like to decide what colour to use to decorate the grade-8 graduation. To do this, she brings a form to every class in her school and asks the teacher to poll the class. Whichever two colours are the most popular are the two she is going to decorate with.

1. What is wrong with Ariel 's technique?

Her technique could go very wrong as each teacher could pick two colors that are really ugly and the dance could look like a whole mess.

2. How could you improve it?

Simply pick the two colors that are simple and pretty; black and silver or white and gold.

# data[].attributes.body
Card A: The sampling technique Joe has used is good in my opinion. Firstly, its unbiased as he his not choosing any students. Its all random thus making it fair. I think of it as Joe standing in a public area collecting data from every other student who walks by, completely fair and unbiased sampling technique. Before anyone says "well its at pizza pizza so its unfair", you're wrong. Just because one is going to eat at pizza pizza doesn't mean its there favourite restaurant. Its actually highly unlikely.

Card B: I believe Carla's technique is most probably flawed. If everyone in gr. 7 and 8 had facebook than it would be fine. The probability of that is really low though. Since they probably don't have facebook, not everyone can answer. Instead of facebook, she can maybe go around each classroom and askn= a few students from each class, or something of that sort.

Card C: Aruns technique is very bias. Firstly, its most likely that the soccer players favourite sport is soccer. This wouldn't be good a good representation of gr. 7 and 8 because he knows the answer is going to be soccer, unless he is dumb. If he had common sense, he could stand outside of pizza pizza and ask every other student who walked in what their favourite sport was.

Card D: Ariel's strategy is pretty good but could be modified a little. Firstly, who cares what the other classes in the school want, the graduation is about the gr. 8's. Its like if you want to buy a Samsung and some other guy wants you to buy an Apple. Who cares what he thinks, its for you, not for him. Also, if he is asking everyone technically it wouldn't be a sample technique. It would a census technique.

# data[].attributes.body
Card A: The technique joe used isn't the best sampling technique, due to the fact that if we wanted to find out the most popular destination for lunch he quite frankly should've just taken and survey and would also save him a lot  more time then just standing out front of a pizza shop trying to count the number of students especially since some of the students who usually go out for lunch may not be there on that specific day.
Card B: I don't believe carla's technique was well thought out at all due to the fact that she posted a post on Facebook asking people to comment for their favourite band, and most of the students in grade 7 and 8 might not have Facebook or even an electronic device in that case.I think she should've put up flyers around her school instead or personally handed them to the students or simply put up a board asking to write down their favourite band.
Card C: Aruns technique was quite absurd due to the fact that he's asking only people on the soccer team what they're favourite sport was, clearly the players would say soccer or else they wouldn't be on the soccer team.He should've went to each team and student and ask them what they're favourite sport is to get a big picture of what each sport others like and collect the data and add up all the different answers to then find out the sport most voted for.
Card D: Ariel isn't being realistic since frankly the other classes and grades don't care what colour the grade 8 grad is going to be since they're not the ones who are graduating and she just taking up time.She should've just asked the graduating class on what colour they liked best and just stuck it at that.

# data[].attributes.body
Card A: Joe's method is not a viable sampling technique. He is missing half of the students buying pizza, so his final answer will be off. He needs to survey all the students buying pizza and find the mode of which pizza was bought the most.

Card B: Carla's method is not a viable sample technique. Many of the students may not even have a Facebook account. If they do, how will they even know about her post. It never said whether she tagged the school or people or whether she even said anything at school. What she should have done is did a school survey or if she did do an online survey, she should have ether done it one a social media everyone has or done something simple that everyone can access like a Google Form. She should've also told the students about the survey to get the most results.

Card C: 1. Ok, here are the problems I see with this. He  asked the PLAYERS on his SOCCER team. He asked only the players o his team, so that itself isn't enough data to represent the opinion of all grade 7 & 8 students. 2nd thing, he asked the players of his soccer team... SOCCER TEAM!!! Obviously 99.9999% of them would say soccer (except that one guy that really hates soccer, but is only there cause all his friends are in it and he doesn't want to go into anything else).
2. He should have went to other students in his school that are grade 7 & 8 about their favorite sport. He can make it easy by using tools like doing an online survey.

Card D: 1. The thing that I see is that it's the grade 8 graduation and she brought every class in her school to decide. Other classes might choose colours that are completely different from what the grade 8s would want. It's their graduation, they should be able to choose for their last moments in the school.

2.  she should've brought only all the grade 8 classed and told their teachers to do class polls with only those classes. That way, it would be the colours that the ones that the grade 8s would want.

# data[].attributes.body
Card A: Joe’s technique to find out the most popular destination to go to lunch is not good. He goes ever Friday to stand outside the restaurant, but that’s only on Friday. What if a grade 7 or 8 come on Tuesday for example, then he misses a person. And another thing is that he is only stand in front of one of the destinations, there are many other. What he can do to make his life easier is go to every class and ask them.
Card B: Carla’s technique is not good. Not many grade 7’s and 8’s have Facebook
and if they do, some students(me) don’t go on Facebook of ten and if something not everyone will see the question. Or they are busy. If something go to everyclass  and ask them.
Card C: 1) He only went to the soccer team, and not only that but not everyone is on a sports team.
2) I would go to each class and drop off a table were they select the sport that they most like, and then collect them at the end of the day. And would a,so tell them to do the table
Card D:1) her method is good, but just make sure that the colors match, and it’s the grade 8’s graduation
2)I say her method is good but I would just as the grade 8 classes what colors, because those are the people graduating

# data[].attributes.body
Card A:
Joe's technique/strategy on finding out the most popular lunch is a very bad one. Since he went to just one "restaurant," and he asks the children the grade 7's and 8's what is their favorite lunch chances are they would say pizza. Why? well its kinda of obvious. Since one would just go to the restaurant that sell one's favorite food.What he is doing would be considered  a sample, which is not his goal. So how does Joe get to the results that would make it a census? Well, Joe has two options. He can either do the easiest one which is to go class to class(specifically grade 7's and 8's) and just ask what their favorite food is. The other option which is the hardest. Is to either ask his friends if they could help him by each one of them stand at a restaurant to ask the question. Personally, I would go with the first option cause it's the easiest and not to mention the most effeciante.

Card B:
Truely Carla's strategy is one of the poorest their are. Not only does she has to go on a electronic to publicate this post but also, not everyone has facebook. Why doesn't she put up flyers while she's at it. Anyways, he strategy is bad because firts of all face book is one of the most used social media's out their. Also, not a lot of people have electronics. Some people with electronic's don't even have facebook. Since some grade 7's and 8's might not have facebook... Well then it becomes a sample not a census. How do we fix this issue? Well, snce she wants to ask specifacally grade 7's and 8's what their favorite rockband is well I think that for once she should put her communication skills to use. veryoen these day's are so use to talk bheind a screen. Nobody really communicates with their voice these days. What she can do is litteraly at any time she wants, she can just swing by a grade 7 or 8 class and quickly ask. How hard is that?

Card C:
What?!!!!!! Arun wants to find out people's favorite sport by asking all the people from a soccer team. What I think he doesn't realize is that if he asks people who are on a soccer team chances are they will say their favorite sprot is soccer. Immediately when he does this, his survey becomes a sample. How would it be a census? Simple litteraly Its the same strategy as I have said before. Go to the classes of grade 7 and 8. Why do I keep on talking about this strategy as the bet one? Well, its because kids have a life outside school, and I don't know about you but if I have to askk a lot of people in my school about one question. Personally the best time to reach them is in class or maybe even at recess.

Card D:
Now, this idea is not completely bad. She gets the idea of asking the class but personally she is overdoing it. She is asking all the classes in her school. Classes that don't care about the colours at the grade 8's graduation ceremony. That's like asking a stranger what colour should you paint your own house. Instead of doint his strategy, to make things easier. She should just ask the grade 8's what colours should the ceremony be. Because at the end of the day they are the only ones that care. Its because they are the only ones graduating.

# data[].attributes.body
Card A:
Joe's method of sampling is not a viable method to use. If he wants to know the most popular place for lunch, he could have asked our surveyed the Grade 7 and Grade 8 students first. Also, wouldn't some of the people who go to Pizza Pizza could be workers, high school students or some adults.

Card B:
Carla's sampling method is not a very good one. There are many things that could happen if she posts it on Facebook. First of all, some people won't be able to respond to the post because they have a LIFE, outside of school or they could be busy (homework, church, chores, grounded...). Second thing is that other people can respond because like so many people use Facebook. What she should do is, she should ask the class instead.

Card C:
Arun is just dumb. There are other people other than his soccer team that would like to vote. Obviously his team will all pick soccer, but there are other people, both girls and boys that would want to participate voting. What I would do is that I would ask other people than my soccer team.

Card D:
Ariel's method isn't a very good technique because first it would take a while and it would take up valuable class time. Plus, isn't this a Grade 8 graduation? So shouldn't she just ask all the Grade 8 classes because that's what I would do.

# data[].attributes.body
Card A: Joe's method of sampling is not a good technique as he is only asking people at the doors of Pizza Pizza. If he wanted to know the most popular place for grade 7 and 8 he would ask before they went for lunch. Another reason why he shouldn't stand outside Pizza Pizza is that if they are going to Pizza Pizza there is a high chance that it is their favourite place. So if he wanted to know the grade 7 and 8 favourite place to eat he would survey children before they left for lunch.

Card B: This is a bad method of sampling. It is not a good technique as it is an online poll on Facebook. The reason why it is bad that it is online is that not many grade 7's and grade 8's have Facebook so you won't get full data. You could improve this by giving a poll to every class to pick up all the data.

Card C: This is one of the worst method's of sampling as she is asking players on the soccer team what their favourite sport is. If she asks all the players on the soccer team what their favourite sport is they will most likely say soccer just like if you ask an NBA player what their favourite sport is they would say basketball. What I would do is give a poll to the intermediate teachers to ask their class so we can get the data from all classes.

Card D: Well she shouldn't be asking every class in the school. It is a grade 8 grad so shouldn't they ask the class that is graduating not everybody. So what I would do is just ask the graduating class which colour they want to decorate it.

# data[].attributes.body
1. Card A: Joe’s method of sampling is not a good technique because if he asks people in front of pizza pizza, it is highly likely that they will pick pizza pizza as their favorite place and therefore it will be biased because it will only be pizza pizza. It will not be proper data and unfair, and the survey will not bet completely true. Instead i would go to and ask a couple people before they go out for lunch where they were going and what place they like to go to lunch to most.

2. Card B: Carla’s sampling is not a good technique because if she asks on Facebook what their favorite rock band is, a lot of people will respond but they are not particularly in grade 7 & 8, so th survey data she’ll collect will not particularly apply to 7 and 8 students. I would instead ask all my grade 8(or 7) friends ad people i know on Facebook what rock band they like.

3. Card C: Arun’s sampling is not a good technique because if he asks all the guys on his soccer team, they will all most likely choose soccer and that is not a good representation of all the grade 7 and 8 students. I would instead go around to each class in grade 7 and 8 and ask one girl and one  boy what sport they prefer.

4. Card D: Ariel’s sampling is not a good technique because if she asks all the grades in her school that would not apply to the grade 8 students. It would be an overall data instead of the specific age group of 8’s. Instead I would ask only the grade 8 students what colors they want for graduation.

# data[].attributes.body
Card A:
Joe's sampling technique is not a viable method. If he wants to try to find out where it's the most popular destination for lunch, he shouldn't just stand by Pizza Pizza. Not only this, but if you're standing by Pizza Pizza, it's not only students who would walk in and out. There would be a mix of different age groups. Some aren't only students. There could be adults who work for a business. It would be better if he were to survey each grade 7 and 8 class instead of standing by an actual waiting for students to go in.

Card B:
Carla's sampling technique is not a viable method. On her Facebook page, what if not many grade 7 and 8's follow her. It won't be accurate as it's not exactly everybody. Also, who is she trying to ask? On Facebook, what if she has other people she knows who are NOT in grade 7 or 8. Her question should be specific to whom she's asking. Instead of asking on Facebook, like Joe, she should go to each class,

Card C:
Arun's sampling technique is not a viable method either. He wants to know the most popular sport for grade 7 and 8 students. Why would he just ask the players on the soccer team? If he wants to know what sport is popular in the intermediate division, he should ask other the students outside of the soccer team.

Card D:
Ariel's sampling technique is a viable method. In her method, she gives a survey to each class for what 2 colors should be used. Unlike the other 3 techniques, this one was the most efficient. However, isn't it the grade 8 graduation? Shouldn't the grade 8's be the ones to choose? Instead of asking every class, she should only ask the grade 8 classes.
