Thanks for the vid. A huge draw back of modern casio calculators (even more advanced models like CG50 or Classpad) is that they don't cater for grouped data. This is a nice solution to get the mean of grouped data, but the calculator is not designed for it. Theres no way to get an estimate for the median, quartiles or interquartile range etc. as we cannot input class boundaries. I really think Casio should think about this. A lot of data we collect falls straight into grouped data. Thanks again for the vid.

Thank you very much! I have a Casio fx-9750GII and i didnt set my 2nd list for frequency as it was set for list 1 for frequency stock. This was very helpful with my statistics homework.

Thank you very much! I didn't realize that I can't put the whole grouped data on the calculator but instead, calculate the midpoint first.

Hi! thanks for the explanation. Do you mind to show me how to calculate the Standard Deviation of a Grouped frequency distribution? Thank you so much!
@aprameyaaithal90713 жыл бұрын
In Stats mode, press Shift 1 for the Statistics Menu, then 4 for Var, then 3 for Standard Deviation

Could you also calculate the standard deviation solely using this method?
@ExamSolutions_Maths10 жыл бұрын
Yes.
@Triarchie10 жыл бұрын
To immediately get the standard deviation from the data input, just press "3" in 8:46

Thank you.. Also I think many people now use the fx-991es Plus calculator, so it might be better using that in tutorials. Nevertheless its doesnt make a big difference
@Triarchie10 жыл бұрын
aman singh To calculate variance, you just have to square the standard deviation, which is the #3 in 8:46

Do you not lose any marks for not showing your method to get the answer?
@ExamSolutions_Maths10 жыл бұрын
You will get the full marks generally if it is correct but the slightest error and you will lose everything as no working can be seen.
