Which factor is NOT typically considered a variable in research?

In research, a variable is any element, feature, or factor that can change or be measured. Independent variables, dependent variables, and control variables are all types of variables that can influence or affect the outcomes of an experiment or study.

Independent variables are those that are manipulated or changed by the researcher to observe the effect on the dependent variable. Dependent variables, on the other hand, are the outcomes that are measured to see if they are affected by the independent variable. Control variables are kept constant throughout the study to ensure that the results are accurate and not influenced by outside factors.

Hypotheses proposed do not qualify as variables because they are statements or predictions about the relationship between variables. A hypothesis outlines what the researcher expects to find based on theoretical foundations and prior research, but it does not change or vary during the study; rather, it is tested through the manipulation of independent variables and the observation of dependent variables. As such, the hypotheses themselves do not fit the definition of a variable in the context of research.
