Hii everyone!!
I'm studying psychology and this semester I'm writing my Master, so I would like to ask about the calculation of sample size. In my research I'm gonna conduct a parallel multiple mediation analysis with 2 mediators and 3 covariate/control variables ( the control variables are from the same scale/questionnaire).
I tried to calculate the required sample size using "Monte Carlo Power Analysis", but there wasnt any option to include the covariate/control variables. Is it necessary in order to calculate the sample size I need to include the control variables? And If so, how can I do it in Monte Carlo Power Analysis"?
Thank you in advance
