Verified step by step guidance1
Understand the definitions: A 'population' refers to the entire group that you are interested in studying, while a 'sample' is a subset of the population that you actually collect data from.
Identify the group of interest: In this scenario, the group of interest is all the students in the class.
Determine the data collection method: You collected the test scores of every other student, which means you did not collect data from every student in the class.
Compare the data set to the group of interest: Since you collected data from only a subset of the class (every other student), this data set represents a sample, not the entire population.
Conclude based on definitions: Since the data set is a subset of the class, it is a sample. A population would require data from every student in the class.
