Statistics - Calculating standard deviation using a Casio fx-115ES Plus calculator

In this video I'll show you how to use a Casio fx-115ES Plus to find the standard deviation for a set of data. Remember that there are two values you could get for standard deviation. This depends if your data represents a sample or a population.

Man, this is so great for the FE exam.
Blessings!

Never in my engineering studies did anybody teach me how to calculate std deviation using casio calculator. It's like 10-14 years ago.
But, still this is worth the info.

I’m currently stuck at the shift 1 part, my calculator is Canon F-789SGA, and it doesn’t return to the stat options once I click Shift 1 since there’s no function on the numbers on my calculator except 9 which is to clear memory. Do you have any tips on how to proceed to get the VAR:’)

Thank you so much sir, you just made things easier for me 🙏❤️❤️❤️

I like your class sir. please make a video on how to find "t" test for one sample nd paired sample
How to test weather data is significant or not.

Thanks!!!! excellent content, you helped me so much :D

[kburgess]

how do i clear the numbers from the memory now????

How can the population standard deviation be less than the sample standard deviation? This is surely incorrect: the population must, almost certainly, have greater variability than any sample taken from it. The sample standard deviation is therefore an underestimate of the population standard deviation. This underestimate is corrected for using Bessel’s correction. On older Casio calculators the notation was sigma_n for the sample standard deviation and sigma_(n-1) for the corrected estimate of the population standard deviation. The newer calculators seem to have the notation precisely the opposite way around.

I just had an exam 30 minutes ago. why don't I see this video earlier TT now
