Question

Mr. Jo Jinho, a senior high school teacher, wants to study the effect of exposure to social media on the reading comprehension of senior high school students in the Cube Academy. A random sample of 350 students was drawn from a list of 1,050 enrolled seniorh igh school students in the Academy. The survey was answered by students (N=290) representing different academic strands: ABM 32%, GAS 11%, HUMSS 19%, STEM 38%. A total of 60 students were not able to participate in the survey due to some reasons..

1. What is the sample size?

2. What sampling method was used by the researcher?

3. Does the sample represent the population Explain briefly.

Answer 1

I do not want to give away the answer as that is cheating but I may help you to figure this out. The sample size would be the smaller amount of students drawn from the 1,050 students. This is because the sample is the students that are actually “tested, surveyed, or experimented on”. The sampling method that would be used did not choose the students in any particular group, category, or reasoning so this means they were chosen “randomly”. If something represents the population it is because the sample was randomized which shows the variety of the senior class instead of a specific group that may affect the results of the study.
