Question

Kristie is conducting a survey for her college newspaper. Because there are nearly 35,000 students on her campus, Kristie decides that she can't survey each student, so she selects a smaller group of students to survey. In this example, Kristie is surveying a __________ of students.

a) Cluster
b) Stratified sample
c) Convenience sample
d) Random sample

Answer 1

Kristie is conducting a cluster sample for her survey on campus. The correct option is A.

Step-by-step explanation:

Kristie is conducting a survey for her college newspaper. Since she can't survey all 35,000 students on her campus, she selects a smaller group of students to survey. The type of sampling she is using is a cluster sample. In cluster sampling, the population is divided into clusters or groups, and then some of the clusters are randomly selected.

All the members from the selected clusters are included in the sample. This method is different from stratified sampling where the population is divided into distinct groups and a sample is taken from each group.
