Dear all, I would like to know which statistical method should I use for my research with SPSS. My research aims at examining the causal relationship of sport training program to academic results. Thus, I collected the academic results before and after the training program from sport participants and also the non-sport participants as the control group. Besides, as I want to know how the training program affects the academics, I also collected the pretest and posttest data of self-esteem and motivation from both experimental and control groups. Thus, I can examine the relationship between self-esteem, motivation and sports. Can anyone help me to solve this big problem for a junior SPSS user? Thanks.
