Answer:

Explanation:
A random sample is a subset of individuals that are randomly selected from a population of interest. Because researchers usually cannot obtain data from every single person in a group due to time, costs and other constraints, a smaller portion is randomly chosen to represent the entire group as a whole. The goal is to get a sample that is representative of the larger population.
