  • @Its_SRRS
    @Its_SRRS 4 роки тому +9

    Dear Tutor,
    You need uniform class interval i.e. of equal size, you've taken the last interval as 90-100 i.e. wrong either it should be 90-99 so that class size remains same or you should make the discontinuous class intervals to continuous class intervals viz. 49.5-59.5, 59.5-69.5, 69.5-79.5, 79.5-89.5, 89.5-99.5 and after this you'll get correct values for M.
    It goes wrong at 2:26
    Hope you'll correct it.

    • @stefandutoit9957

      Considering that these are grades and some individuals are capable of achieving 100%, wouldn't it make more sense to include 100? (Not trying to crush your comment, I'm just trying to gain more insight)

    • @Euleogy
      @Euleogy 4 роки тому

      I noticed this too. For the ranges I would do 51-60, 61-70, etc etc. And then for your midpoint it's not 60-51, you're supposed to find the difference between the lower class limits. So it would be 61-51= your class limit = 10, then the midpoint is divided by 2, so 5. You CAN do this kind of thing with uneven class sizes, such as 0-60, 61-70, etc, where your lower class is a whopping 60 (midpoint of 30). You just have to multiply that frequency by that specific midpoint.
