Thank you so much, it help me do my Math homework🙏🙏🙏

[@missykim9136]

Please can be it used for both grouped and ungrouped data?

Thanks a lot !

Idk if my calculator has that cuz the model in this video is Casio, But my model is Sharp-

[@sportygamer7464]

But when I work it out using the formula I get the sx value ?

[@lita1019]

why u didnt choose the 4th one? sx? what’s the difference? i thought sx is the one with population which means per (n-1)

[@HoangMaths]

Sx is for sampling data.

Dear sir can you have any trick to find how often a number is repeated(frequency )by using calculator

[@HoangMaths]

Hi Sarah, Yes I do, it is on the link below from 5.45 minutes. kzbin.info/www/bejne/fITFgoirobOej5Y Hope this helps.

How to clear the data sets?

@Akroia the link below will help you to clear all the data. kzbin.info/www/bejne/l5-8dnZ9Zcd1bMU

@@HoangMaths Hi I'd like to know how to set n-1 part? The formula is (X- x̄ )²/n-1 right?

[@HoangMaths]

@@akroia1986 to do manually it is a very long process you almost got the formula right, and that is for sampling standard deviation. For population just divided by n instead of n-1. very hard to type equations here so please check on the links below for the correct formula. www.scribbr.com/statistics/standard-deviation/

[@akroia1986]

@@HoangMaths Oh so it's not possible to set sample(n-1) variance in classwiz. Noted thank you.
