Step 1

The dependent variable in this study is the sleeping time (in minutes) of the adult insomniacs. This is because the sleeping time is what the researchers are measuring and is expected to be affected by the type of pill (real or fake) given to the participants. Show more…

Key Concepts

Dependent Variable

The dependent variable is the outcome that the study measures—it's what is expected to change as a result of the manipulation. In experimental designs, this variable is observed and recorded to determine the effect of the independent variable. In more general terms, it is the consequence or the effect in a cause-and-effect study model.

Independent Variable

The independent variable is the factor that is manipulated or varied by the researcher to observe its effect on the dependent variable. It represents the presumed cause in an experimental study, allowing the researcher to establish a cause-and-effect relationship by comparing responses under different conditions.
