Simple Random Sample At a national conference of the American Appliances Association, a market researcher plans to conduct a survey of conference attendees. She uses the list of attendee names and selects every 20th name. Is the result a simple random sample? Why or why not? In general, what is a simple random sample?

Answer:

Step1 of 3:

We have At a national conference of the American Appliances Association, a market researcher plans to conduct a survey of conference attendees. She uses the list of attendee names and selects every 20th name.

Step2 of 3:

We need to check whether is the result a simple random sample? Why or why not? In general, what is a simple random sample?

Step3 of 3:

“No, it is not a simple random sample” because it is a systematic sampling method. A simple sampling method a sample of n subjects is selected in such a way that every possible sample of the same size n has the same chance of being chosen.

simple random sample: A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen.

For example: In a medical study, the population might be all adults over age 50 who have high blood pressure.
