Problem
Lucian is a school counsellor. He wants to raise awareness of student cyber-bullying with the students' parents. Lucian therefore wants to find out whether students at the school have discussed the issue with their parents. a. Explain why it might not be practical for Lucian to use a simple random sample or systematic sample. b. Lucian wants to make sure that each gender is appropriately represented in his sample. Should he use a stratified sample or quota sample?Intuitive explanation
This is a sampling and inference problem: you're trying to estimate a population proportion (what fraction of all students discussed cyber-bullying with parents) based on a sample. The key insight is that a well-designed sample lets you make reliable claims about the whole school without surveying everyone. You'll need to think about how to choose students fairly, what sample size gives you confidence, and how to interpret results—recognizing that any sample has natural variation from the true population value.
