A sample of the students at a middle school is selected by writing the name of every student in the school on a slip of paper and putting all the names into a bin. The bin is then rotated to mix the slips of paper and 25 names are drawn without looking. If the bin is rotated after every draw, which kind of sampling method is this?

Question

A. Non-random sampling
B. Simple random sampling
C. Stratified random sampling
D. Systematic random sampling

Answer 1

The sampling method described in the question is known as "Simple Random Sampling." In this method, each student in the school has an equal chance of being selected for the sample. The process involves randomly drawing names from the bin after rotating it to ensure a random selection for each draw.
