[@omaryheyttey179]

hey this is very nice videos, which software are you using to attach calculator on the screen like that, thanks very much, i enjoy your videos

[@mrraynermaths4118]

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.

is there a way to see the Quartiles, percentiles & Deciles in this calculator ?

[@mrraynermaths4118]

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.

[@lucianosaldivia5917]

In case you need this:
type_A_uncertainty = st_dev(X) / sqrt(n)
Being n the number of samples.
