Question

Using a table of random numbers, the sample of 400 subjects was selected from the list of the license numbers of all registered nurses in the state of Michigan. Each nurse was sent a letter requesting completion of an online survey on workplace bullying. This is an example of what type of sampling method?

a. Simple random sampling
b. Quota sampling
c. Convenience sampling
d. Purposive sampling

Answer 1

a. Simple random sampling

Step-by-step explanation:

A simple random sampling is a subset of individuals (the sample) selected at random from a larger set (the population) by a process that ensures that:

• All individuals in the population are equally likely to be chosen for the sample; and
• Each possible subset of individuals (sample) is just as likely to be chosen as any other subset of individuals.

An example of simple random sampling can be seen in the question above, where a sample of 400 individuals was selected at random from a much larger group of people.
