Verified step by step guidance

1. Understand the definitions: A 'population' includes all members of a specified group, while a 'sample' is a subset of the population.
2. Identify the group of interest: In this problem, the group of interest is 'every student in a class'.
3. Determine the data set: The data set consists of 'every other student in a class', which means not all students are included.
4. Compare the data set to the group of interest: Since the data set does not include all students, it is a subset of the population.
5. Conclude that the data set is a 'sample' because it represents only a part of the entire group of students in the class.
