Amount of sample members

Postby Claudia468 » Tue Oct 19, 2021 7:39 pm

Hello, I'm a junior and I'm having trouble deciding how many sample members I need for my science fair project. I tried searching up online how to determine that but I didn't understand. Basically, I'm trying to survey high school students from grades 9 to 12. In my school, there are two classes for each grade (two 9th grades, two 10th grades, two 11th grades, and two 12th grades). I want to test what are the causes of stress in teenagers from different teen ages in a survey. As my hypothesis, I wrote that school will get the highest out of all the causes. I want to know how many people I will be needing from each grade.

This sounds like an interesting project! Here is the link to a Science Buddies resource that explains how many survey participants you need to get accurate results.
