The essential variables in any research study are the independent variable and the dependent variable. The independent variable is the variable being manipulated or tested in the study, while the dependent variable is the outcome or result that is being measured. The subject variable may also be important in some studies, as it refers to any characteristic of the participants that may influence their response to the independent variable. However, it is not always necessary or essential to include a subject variable in a study. The predicted variable is not a commonly used term in research, so it is not a relevant choice.
