Independent variables are manipulated by the researcher in such a way that allows the researcher to conclude the independent variable either causes or does not cause the changes in the other variable or outcome. The predictor variable in this example is education level. I would like to build the model A~B,however, I have observed that A moves up earlier than B and much faster. d. one independent variable, If your analysis notes that participants in a weight loss study differ in amount of weight lost based on their gender, what type of effect is this called?
