Answer to Question 1

In research, we use random selection to generate a random sample from the population. The sample is the group of people we study and the population is the larger group of people about whom we are trying to draw conclusions. When we randomly select, we are more likely to draw a sample that is representative of the population, or like the population on important characteristics.
