    @AdekoyaGbemisola-d5c 21 день тому

    Thank you for this video Abefe 1. To clarify, for dependent samples does it mean the samples have to be of equal sizes? Also i think there is a mistake from the screen pop up for alternative hypothesis, it is denoting it as H0 2. You said independent t-test is used when you can't satisfy the normal distribution but then again it is a parametric test(which are used for normal distribution) , can you help me clarify this

    • @MLS_byAbefe
      @MLS_byAbefe 21 день тому

      To answer your first question. It is a paired sample test, emphasis on “paired” meaning that have to be the same size. Thanks for pointing out the error by the way. For your second question, some distributions can be so similar to the normal distribution and this is where the t distribution comes into the picture. A non parametric test is in no way similar to a normal distribution

    There is no connection between peak and tails. You can have infinitely peaked distributions with very light tails, and you can have low, flat-topped distributions with very high kurtosis. Examples of these distributions are given in the Wikipedia page.
