Question

A treatment variable, also known as an experimental variable or manipulated variable, is the variable that is changed or controlled by the researcher in an experiment. It is considered crucial in estimating outcomes because the researcher has control over its manipulation, which helps to minimize variance and increase the accuracy of the results. Independent variables are also important in experiments, but they do not necessarily have the same level of control as treatment variables. Dependent variables are the outcomes being measured, and random variables refer to fluctuations that are not controlled by the researcher, so they are less crucial in estimation.
