Answer: A. Random assignment
Explanation:
During a social work research, a group is created to test the reliability of the results. The people in this group are not given any treatment and if they are, they are given a different treatment. Depending on whether the group was randomly chosen or not, this group is called a comparison group or a control group. While a control group is randomly assigned, a comparison group is not.
It’s important because you need to be able to tell people how you feel & understand how others feel . Instead of keeping all your emotions bottled up.
