Видео

Dear lecture! The video is very useful for my research.

Very worst video this is , he just want to waste time on this video, no any information given only making fool through this video, why RUclips can't take these things in seriously to ban these kind of people

Very useless explanation and unnecessary talking 😢

So much useless speach.

I saved my file on spss but when I want to retrieve it, it is not saved. What happens here?
