Sampling Techniques - Math4 - L2 by Mr. Migdal https://padlet.com/arturmigdal/lm7tevhyrwp2 See OneNote for the 4 cards en-us 2016-12-14 11:04:48 UTC 2025-10-05 21:55:29 UTC hello@padlet.com Michael Carvalho https://padlet.com/arturmigdal/lm7tevhyrwp2/wish/143835904 CARD A
This survey strategy does not work properly because he only surveyed one food place. And because students are there, it is most probably their most preferred place to eat. He left out all the other students that go into didferent food places. 
CARD B
This survey strategy does not work because many different age groups may k]]> 2016-12-15 14:04:48 UTC https://padlet.com/arturmigdal/lm7tevhyrwp2/wish/143835904 Rachel https://padlet.com/arturmigdal/lm7tevhyrwp2/wish/143837811 Card A: It is not a good idea because if he only stands outside Pizza Pizza, everyone is going to say they like Pizza Pizza, or they wouldn't go there. A better solution would be to take a sample size. 

Card B: That is a good idea because she will direct answers to the question. 

Card C: Arun's technique is not the best because on his soccer team, most of the people will say soccer is their favourite sport. He could improve by taking a population at his school. 

Card D: Ariel's technique isn't the best because there is going to be more than 2 colours, so it is going to be hard to count all the colours from the classes. She could improve this technique by picking a certain number of colours and doing a census with the grade 8's. ]]> 2016-12-15 14:10:59 UTC https://padlet.com/arturmigdal/lm7tevhyrwp2/wish/143837811 Isabella https://padlet.com/arturmigdal/lm7tevhyrwp2/wish/143839103 Card A: This sample technique]]> 2016-12-15 14:14:46 UTC https://padlet.com/arturmigdal/lm7tevhyrwp2/wish/143839103 Victoria 073643090 https://padlet.com/arturmigdal/lm7tevhyrwp2/wish/143839510 Card A: This sample technique does not work because it is bias. This is bias because Joe is surveying people outside of Pizza Pizza. If he does not want it to be bias he should ask people in the hallways instead of a certain place like Pizza Pizza. 
Card B: This sample technique could work because she's just asking people online about their favourite band. 
Card C: 
1. This technique wouldn't work because it is bias. 
2. Instead of asking specifically people on the soccer team Arun shouldn't go up to ac certain team and ask him. Instead he should go up to random people and ask them. 
Card D: 
1. The method is okay, as it is not biased. The only problem with this technique is that the two most popular choices could be from the younger kids. If I were to put together the 8th grade graduation I'd asked only for their opinion because it's their graduation. ]]> 2016-12-15 14:16:01 UTC https://padlet.com/arturmigdal/lm7tevhyrwp2/wish/143839510 Kaya https://padlet.com/arturmigdal/lm7tevhyrwp2/wish/143839837 Card A: This sample technique is not effective at all because when standing outside of Pizza Pizza, there is bias in the survey, most people will most likely be going to Pizza Pizza to buy pizza rather than other food.

Card B: This sample technique is a little more effective than the other one, however different age groups may not enjoy listening to the same music, or may not even have social media to respond to the survey.

Card C: 1) When Arun asks his soccer team, there is a lot of bias in the question because the soccer players are devoted to the sport and enjoy playing that sport. So they will obviously choose soccer. 
2) Arun could ask other people, rather than his soccer team. Arun could ask his peers at school or friends and family members.

Card D: 1) She is asking more than one class, so that must mean that there will be more than two colours she will have to choose from. For example even if there are two classes there are four colours, she must pick two out of the four, which may not be the colours the class had wanted. 
2) Ariel could improve this by asking each classroom to take a vote for two specific colours they like. Another way she could do it is she could take the previously collected data and make a survey which students like the two colours best out of all the possibilities.]]> 2016-12-15 14:17:18 UTC https://padlet.com/arturmigdal/lm7tevhyrwp2/wish/143839837 Gillian https://padlet.com/arturmigdal/lm7tevhyrwp2/wish/143841219 Card A- this sampling technique will not work because obviously there is a bias if he will be standing outside of a Pizza place.
Card B- this sampling technique will work because there is no bias.
Card C- this sampling technique won't work because there is a bias. Most of the players in his soccer team will pick soccer. 
Instead, he should ask his class or the whole school.
Card D- sampling technique is effective]]> 2016-12-15 14:22:12 UTC https://padlet.com/arturmigdal/lm7tevhyrwp2/wish/143841219 Heather https://padlet.com/arturmigdal/lm7tevhyrwp2/wish/143844278 Card A: this technique will not work as the pizza place is not the only lunch place that there is. He is being bias and will therefore not learn the most popular place as he is only observing one place. A survey would have been much better. 
Card B: I think that this will be a good idea , as facebook is a popular site and she will be getting different answers to her question. 
Card C: this technique is wrong as he is asking people on the SOCCER TEAM what there favourite sport is? I am pretty sure their answers will be soccer. He should ask the entire school with an online survey, so that he will receive more answers. 
Card D: This technique is not very effective as she is asking different classes. Each class wil have 2 different top colours. This will resolve in too many different colours for her to choose from. What would have been better would be an Online survey with everyone's answers which would make choosing easier and as well comparing the results. ]]> 2016-12-15 14:30:51 UTC https://padlet.com/arturmigdal/lm7tevhyrwp2/wish/143844278 Dominic https://padlet.com/arturmigdal/lm7tevhyrwp2/wish/143848178 Card A: this technique won't work because he is surveying only one place. Since there are students there, that place will probably be the most popular place for lunch.His technique was bias therefore he will not get the real most popular place to eat.

Card B:it was a good idea but the only problem is that she might get different types of rock bands so it might get hard to find the most favourite rock band.

Card C: his idea was smart because he's asking a soccer team what is thier favourite sport which would be soccer. He's is asking a bias question. He could have asked what soccer team is your favourite.

Card D: she asked every class and not only the grade eight class or classes. To improve her technique she could only the grade eight class or classes.]]> 2016-12-15 14:41:03 UTC https://padlet.com/arturmigdal/lm7tevhyrwp2/wish/143848178 Michael Carvalho https://padlet.com/arturmigdal/lm7tevhyrwp2/wish/143849102 CARD A
This survey strategy does not work properly because he only surveyed one food place. And because students are there, it is most probably their most preferred place to eat. He left out all the other students that go into different food places. In order to get trusted results, question students where there is no restaurant or food plaza nearby.
CARD B
This survey strategy does not work well because a range of age groups may answer this question. Also, there are many grade 7 and 8's that are not on Facebook. So, to get more accurate results, you must direct this questions to only the grade 7 and 8's. Once you find sufficient information, create options for the students and make a t chart to organize your data.
CARD C
The problem with this survey strategy is that Arun went to a group of people that creates a biased answer. To get more accurate answers, survey a diverse group of people that cannot specifically be in a certain group of sports. 
CARD D
She is questioning all the grades. This creates more chaos because all the grades except the 8's are not involved in the graduation. Therefore, to fix this problem, she must survey only the people that are involved in the gradation.

There could be other student's who eat at different places other than pizza. A different strategy to collect that data is to stand at a place where all the student's regularly go, like ; in the cafeteria or in a local area in the school.
Card B: This is not the best sampling technique because maybe not all the student's are allowed to use social media or have facebook at all, but it is more effective that the other technique. Most students have facebook and reading the answers is easy to do. To improve, she could ask on more social medias, because majority of teens have social media, like Instagram and snapchat.
Card C: 1. He's not asking all the student's and he is being biased, leaning only towards soccer players. 
2. Ask student's while they are at gym class. The student's are playing sports they enjoy, and you are including everybody into your sampling. 
Card D: 1. The thing that is wrong with Ariel's technique is that she is asking grade 7 & 8, and the only people actually involved in the graduation are the grade 8's. She is also going to have lots of work to count all of the information/ data that she collected. 
2. She could improve her technique by only asking grade 8 student's and by making an online survey, which will count the data automatically so that she has less work to do.]]> 2016-12-15 18:25:48 UTC https://padlet.com/arturmigdal/lm7tevhyrwp2/wish/143920687 Martyna https://padlet.com/arturmigdal/lm7tevhyrwp2/wish/143982318 Card A:
In my opinion, I don’t think that would be a good place to have a survey because not everybody likes pizza. This survey would be inaccurate and not fair because he will only ask the people who are going to pizza pizza and they like this place so they would say pizza. To get a fair and accurate survey he would have to stand in front of the school so when they are leaving for lunch he could ask them which lunch destination they’d prefer.
 
 Card B:
In my opinion, I think doing a survey on Facebook would be a good idea. Many people have Facebook, so it would allow lots of people to see it. The one thing I would change about this is by listing 3 different types of Rockbands for people to choose from. If they were all to write different Rockbands, I could have a list of 50. Also on Facebook, there is an option to make a survey, which makes it even easier.
 
Card C:
1)    His technique is wrong because he is only asking people from the soccer team. Evidently, the soccer players would only choose soccer. 
2)    In order to improve this, I would ask people in the schoolwho don't play sports so there would be a variety of different answers. Also ask around the gym.
 
 
Card D:
1)    Ariels technique is wrong because she shouldn't go to every class in her school. 
2)    Since it is the grade 8 graduation, she should only go to the grade 8 classes. The two colours that are the most popular would be chosen.
