Hi, thanks for the comment. I usually use Powerpoint to write on, Zoom/OBS to record, Casio Emulator for the calculator and AutoHotkey to keep the calculator on top. AutoHotkey uses scripts to force a program to remain on top of others. The one I use is called AlwaysOnTop. AutoHotkey: www.autohotkey.com Calculator: edu.casio.com/softwarelicense/index.php

Hi - there is a way to see the quartiles, but not the percentiles and deciles. Once you have entered your frequency table, you want to press "shift" and "1" to enter the statistics calculation mode. On this mode, you want the minmax function to get the 5 number summary. This will be the min, max, Q1, 2 and Q3 of the data input.

yea but he never wanted you as a student.

You're welcome! Let me know if there are other areas you would like to see.

@@mrraynermaths4118 Hi sir, Faturoti favour would like a video on moments if that's possible. Kindly appreciate it.
