A researcher has a population of 100 individuals and needs 10 subjects. He randomly divides the sampling frame (100) by the required sample size (10) and uses that number (10) to pick people in the sampling frame. So, he picks every 10th individual

A researcher has a population of 100 individuals and needs 10 subjects. He assigns all individuals a number and randomly selects the numbers.
