Thank you Dr Aryadoust for these clear and easy-to-follow videos. I have a question, can you tell me which test to use if I had two separate groups (control and exp) tested on two occasions (pre- and post tests) , sample size of each group is 62, non-parametric data, one independent variable and one dependent variable (ordinal)
You might want to try mixed ANOVA. Between subject variable: groups. Within subject variable: occasions. You could also do the same type of analysis using non-parametric tests available in SPSS.
Please in this example, can one use an alpha value of 0.05 for one T-test and use an alpha value of 0.01 for the rest of the T-test in the same study or analysis?

Hello, why does the non-normality of HDHF affirm the significance of it in Mann-Whitney?
Not sure what you meant.

Right. I guess that would be Friedman test. Thank you once again!

I suggest one alpha value be used, either 0.05 or 0.01.
@@VahidAryadoust Thank you Sir. Your videos have been very helpful to me.
its not really useful to just read the button describtions and never really explain anything.. thanks i guess, tho.
