Hello, experts!
I am doing my research by using AHP method. I have 4 main criteria, 14 sub-criteria and 5 alternatives and I have 30 experts. I have already done AHP analysis. But I need to do reliability test and validity test of my questionnaire and survey results. I want to use SPSS. I don't know how to use SPSS. Step-by-step guides would be greatly appreciated!
