Tell whether the sampling strategy will result in a random sample from the population under consideration. If it is not random, explain why it is not.A researcher wishes to survey a random sample of high school teachers within a certain school district. There are 77 high schools in the school district. She lists the schools alphabetically and uses the calculator command to pick five numbers between 1 and 77. She visits the five schools corresponding to those numbers and interviews all teachers at each of the five schools.

Question

What will be an ideal response?

Answer 1

This is not a random sample. The teachers will come in five chunks, each chunk consisting of a group of colleagues. This could result in an unusual number of teachers in the sample who are colleagues. Colleagues are more likely to share similar backgrounds, experiences, and opinions.
