In my research I have 4 independent variables which are gender, BMI, department, and hours spent on computer and two dependent variables which are test scores for two different tests (SSS) and (FSS). The test scores (SSS) and (FSS) and the independent variables were obtained from the same population which is 100 students. So basically each student of the 100 students answered a questionnaire which contains the variables gender, BMI, department and hours spent on computer and also he/she answered the SSS and FSS tests.
There was a research where they did one way anova separately for each of 5 catagories, I added the image for this.
I wanted to know if this is the correct method? Can I do anova separately for each catagory?
