    Really clear explanation. It does all make sense now. Besides the way the teacher speaks is really lovely. Thanks for helping me learn more. Greetings from Colombia

    The best thing to do is to just skip a stupid p value test like the Levenes test and just assume the Welch correction anyway (as recommended by Andy Field)

      can you recommend one of his books, I can see most of them are on SPSS but I'm learning STATA

      @@fajrelbanna4570 i have the story book called 'an adventure in statistics' , the SPSS book and the R book(I also preordered his new version of the R book). I think STATA is fine and it's an easy switch from a other GUI based data program. I myself started with SPSS, went to jamovi/ jasp and atm I'm solely using R. Didn't take too long to switch ☺️

    Hi! Great video....
    My question is: Why do you need equal variance between groups?

    • @ecoarena

      Unequal variance can result in bias and inconsistency when calculating particular statistics such as standard errors and confidence intervals
