    My brother studies Mathematics and Statistics at Bells University of Technology. He's currently in 200lvl, and he's offering Power BI, Excel, and Python as courses. So, the undergraduate program for Data Analyst wanna bes would probably be that program. Of course, do some research and decide if that's what you want to do as an undergraduate. I hope this helps someone.

    i have a very puzzlingly question based on what you just explain, in a football match which is a typical case of an experiment which has ONLY three possible outcomes meaning the probability of a win or loss and or draw are pretty much the same. we agree on that. have you ever been in a situation with a group of friend whereby you guise for instance agree that the probability of a small team of football like india (which has never participated in any tournament in the past, thus has no skill, no tact etc... ) suddenly face a team like brazil will not in any possible way beat brazil. in other words, all of you agree that brazil has 95 to 98 percent chance of beating India. SIR!!! how can we write or express this kind of probability knowing that there is only three possible outcome ( or sample space stays the same )

From your analysis, Furnitures has more demand which generates more sales but the discount is affecting the profit margin. Is it possible instead of avoiding furnitures entirely, they should reduce the discount rate. What do you think?

    @AdekoyaGbemisola-d5c 4 หลายเดือนก่อน

    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 4 หลายเดือนก่อน

      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
