This research uses two variables, the dependent and independent variables. Correlational studies. Oxford: Oxford University Press. Sometimes you may hear this variable called the "controlled variable" because it is the one that is changed. Wandersman., eds. 1996. 1978. The researcher is able to identify any potential confounders that may be influencing the outcome of the study and draw conclusions about cause and effect relationships when they are aware of which variables are dependent on one another and which variables can be considered independent of one another.

In research, variables are any characteristics that can take on different values, such as height, age, temperature, or test scores. The dependent variable, then, is one that depends on, or is influenced by, another variable.
