Research Notes

Question – Ex post Facto research

Answer – In such research, independent variables or variables have already occurred, in which the researcher begins with observation of a dependent variable or variable. Then he studies the independent variable for its possible relationships, depending on the variable or variables dependent in the retrospective variable. The most important difference is the control between experimental research and ex-post-actual research. In the past, there is a manipulation control on the independent variable of the investigator, while later this control is not possible, more than that, randomization is not possible.
