In a survey of TV viewing preferences, 100 people are chosen from each age bracket: 15-20, 21-25, 26-30, etc.
Is this a random sampling? Is it a simple random sampling
Homework Answers
Yes, this is a simple random sample, as a simple random sample is a subset of individuals chosen from a larger set where every individual is chosen randomly and entirely by chance, such that each individual has the same probability of being included in the sample.
Here the larger set is the age groups from which we select people randomly with equal probability of inclusion .
