Ms, Alvarez wants to determine the seventh grader's preferences for the location of the end-of-year field trip. Which of the samples representative of the population?

A.  All students in Ms. Alvarez's fifth-period class

Step-by-step explanation:

The options are missing, so I looked them up:

A.  All students in Ms. Alvarez's fifth-period class

B.  All students in Ms. Alvarez's advisory group

C.  Every third student from an alphabetical list of all students in the entire school district

D.  Every fifth student from an alphabetical list of all seventh graders in the school

In statistics, the population is the whole number of people (or data) where you can draw a sample from, i.e. the population is the whole group, while the sample represents a smaller number of people that participated in the study or survey.

Options C and D are wrong because a population must include all possible subjects and not just every third student or every fifth one. Option B is also wrong because I doubt that all seventh graders are in her advisory group, since advisory groups tend to be relatively small. The only option left is A and it would be correct if Ms. Alvarez's fifth-period class  included only seventh graders (which is more plausible).
