Question

Sima believes that wearing black clothing causes people to behave more aggressively. In her experiment, she randomly assigns people into two groups. In group A, participants are given black shirts to wear, while participants in group B are given white shirts to wear. Each participant is then asked to play a violent video game for fifteen minutes and his or her score is computed. In this experiment, each participant's video game score is the _________ variable.
A) dependent
B) random
C) independent
D) confounding

Answer 1

Answer:

Dependent variable

Explanation:

The dependent variable is the variable that is tested in an experiment and that can not be manipulated by the experimenter. It is dependent on the independent variable.

Whenever the experimenter manipulated the independent variable, the effect of independent variable manipulation can be noticed on the dependent variable. These both the variable can be noticed in the form of cause and effect.  

Thus Sima used the video game as the dependent variable that can not be manipulated but the independent variable such as shirt can be manipulated and can see the effect of shirts color effect the video game.
