A psychologist was interested in the effect of attractiveness on perceived behavioral problems. Student teachers were asked to read a description of a girl who had acted out a bit in class (talking when she wasn't supposed to). A picture, supposedly of the girl, accompanied the written description. For some of the student teachers, the picture was of an attractive little girl. For other student teachers, the picture was of an unattractive little girl. Then they rated the girl on a seven point scale indicating the extent to which they thought she had a behavior problem in class. A. Independent Variable (IV):_description/ picture of girls 1
B. Levels of the IV: _.
C. Dependent Variable (DV): _attractiveness_

A. Independent Variable (IV): description / picture of girls

B. Levels of the IV: two levels

C. Dependent Variable (DV): attractiveness

Explanation:

The above experiment presents two levels of independent variable.

In summary, we can say that these levels are related to the number of experimental conditions that the independent variable can cause. As shown in the question above, the independent variable is the girl's photo and description. The conditions that this variable can cause is to stimulate attractiveness, or to discourage the throughness of those who observe it, that is, there are two conditions, so there are two levels of independent variable.
