Question

A professor computing the sample average exam score of 20 students and using it to estimate the average exam score for the 1,500 students taking the exam is an example of inferential statistics. True or false?

Answer 1

Answer: True

Explanation:

Inferential statistics are based on taking data from a sample (in this case the 20 students represent the sample) of the population to be studied, and from them get a conclusion (for example, average score, etc).

The purpose of the conclusion or conclusions obtained from the sample is to generalize them for the entire population (in this case the 1500 students).
