An experiment was designed to determine if gender of the interviewer and the amount of eye contact by the interviewer will influence the participant's liking of an interviewer. Thus participants were randomly assigned to groups that had either a male or female interviewer who made little, moderate, or sustained eye contact. At the end of the sessions, the participants were asked to rate their liking of the interviewer. This is a design.

This is a between-group design.

Explanation:

Between-group or between-participant design refers to the design of experiments that involve two or more groups being tested simultaneously but with different factors. The simplest way to carry out a between-group design is by dividing participants into two groups, the experimental one and the control one. In the situation described in the question, we have several groups, all with different factors being tested at the same time.
