Sampling techniques & Statistics (Renzo)

# data[].attributes.body
I choose sampling techniques because I think it's the most useful unit I've learned compared to the others. It's commonly used in our daily life such as the statistics we see in the news that use sampling techniques, etc. This is a very useful thing to learn in math to use in real life.

i think that sampling techniques could relate to many real life context.
for example: what ages ages are vulnerable to Covid-19. research question: what ages are vulnerable to covid-19?

i choose statistics because this particular technique is common but very usefull indeed, this technique could really be helpful to observe problems that occurs in real life.
example: conducting a survey on problems that are related on population.

I choose quadratic function as my topic. It will help me to record data with quadratic function. For example throwing a ball to the air and fell to the ground, then turn it into 1 graph to see the equation and what type of function is it. Or I could also see the graph of covid cases predictions and how to prevent the virus.

Probability is advantageous for a researcher that conduct different types of experiment. Probability has a system that could generate a conclusion without exploring each answer for every single population in the range of the experiment, which makes it interesting. It is also easy to use and it has different types of ways to collect the population/subject to interview.

I choose sampling techniques or statistic because is the best thing we can do that impact to real life society.
Example: We can do survey to how much time we spent time in our phone. How much time do kids nowadays spent watching youtube and play phone.
From that problem we can research the impact of playing phone to the kids and to us. so sampling techniques is the best for real life problem.
Research question:
How much time do adults and children below 12 years old spent their time in phone. and whats the impact.

Sampling techniques can be used to select an individuals or a group of people in a surveys. For example: selecting which type of people who's age is 50+ who voted in a selection
Research question: In a election, will a young person (18-28 years old) vote will usually be different then people who are 50-65+ years old?

- Sampling techniques has a wide array of examples and problems to choose from, and with that it will be less time consuming when preparing for the project. not only that but sampling techniques are more or less made for researching, conducting surveys, projects, hence why it is a perfect choice for this math fair
Example: Conducting a survey where questions appearing on the topic of Social conflicts, Social issues and/or social politics will be asked. Which then the answers to such question, will be throughly analyzed, and furthermore making a final report
Research question: Since i have yet to exactly pin point as to what i want my research to be about, i'm not quite sure as to what my research question should be about

# data[].attributes.body
-In statistic its easy to raise a problem where we need to take one problem that occurs in real life and use sampling techniques on the process of researching. The problems that we can use are for example the population of people who has voted, covid cases, and other real life problems
-Research question: worldwide which population has the most cases of covid 19, including people who are positive, carrier, and negative, why, and what way can we help to prevent it?

Reason I Chose (Including Examples):
I feel that Survey Sampling is somewhere in my field of interests as it has quite the versatile use. I also have this particular feeling of "fun" towards Survey Sampling in which I mean it can be messed around with, professionally speaking. Furthermore on versatility, Sampling can be applied to a lot of conflicts around the world wherein certain examples may include asking people a few or maybe more questions with the general idea being finding out what they think about a certain conflict to compare their different responses to see what the majority is saying or possibly making a sample of the population of a village and surveying the sample based on education to determine a country's overall educational adequacy and sufficiency. The previous example even shows that if we do not have enough time and/or resources to survey the intended target/amount of people, you can take a sample from that amount through various techniques to find the nearly most accurate results to when compared to the results of surveying the intended amount. Simply put, it's practical and time-efficient.

Background Problem:
According to UNICEF, there are approximately around 153 million orphans worldwide and that number is only increasing with each passing day. Now I understand that there are certain orphans whose parents might have possibly passed away for reasons I won't touch upon and because of that, I am not able to help them wherein the context does not apply. The context does, however, apply to orphans whose parents left them at foster care/orphanages and the context/problem is that parents leave their children at said foster care/orphanage (sometimes) without any explanation or reason for the child to understand. I want to help these children somehow in finding their parents by using the knowledge I have about survey sampling and how it can connect to science. An assignment me and the rest of the class had to do in Mathematics was to collect data based on genetics by surveying people about themselves and their parents wherein the information we used to determine the likelihood of parents having produced said person we surveyed. Maybe there's a possibility I can somehow reverse engineer this process with orphans by asking them their genetic information and then somehow have access to a wide range of information of parents who may be related to said orphans that are found in the general vicinity or maybe even the entire country. I want these orphans to reconnect with their family or maybe just help them answer the question they've sought after for their entire lives, or at least for as long as they've been an orphan; "why?"

Research Question:
I suppose that judging from my background problem that my Main/Research Question should be about orphans finding out the reason why they were left at an orphanage or at foster care and possibly also about the arduous journey of finding said parents. Maybe it can go something like this:
"What is the leading reason for parents to be leaving their children and how difficult may the task be/will be of finding said parents?"

I chose sampling techniques because it could be applied to

I choose the topic of quadratic function and problem related to real-life context.
Example: Modeling the problem of thee bus and draw the graph of bus moving.
Research question: What kind of quadratic function that model the bus moving ?

i choose sampling technique or statistics because i feel like i'm good at doing statistics and i love sampling techniques, also it can relate to many real life context

example: the covid 19 case we can use sampling techniques to differentiate the difference of the number of people affected to the virus from different countries

research question: the difference between /the covid cases in indonesia and other countries
