i swear i knew you were asian the moment you said ''throw it away'' and 'efficently '' its ablosutley like how my chinese friend talks like haha thank you for the vid!!!!!!
interesting findings! I am also a hongkonger myself and I do use these terms quite often. So how do native speakers express "throw it away" and "efficiently"?
that's "Sample standard deviation". calculated by sqrt((sum of all "square of difference") / (n-1)) Reference: www.thoughtco.com/calculate-a-sample-standard-deviation-3126345
hey - a freshman here - is there any way to find the sample statistics instead of population parameters by using the SD mode? For example, standard deviation for sample is calculated by squared deviance divided by (n-1) instead of n for population. Thanks :)
May I ask why nothing happened when I pressed 10 and then M+ despite that I have done all the steps you mentioned before it? ( I didn’t press shift 9 3 and the model of my calculator is the same as yours)
@@HWei-ju8ut oops then I have no idea... You may try again exactly these procedures: Mode 1 (COMP) Mode 4 Shift - 9 - 1 EXE 10 M+ (then you will see line=1) 20 M+ (then you will see line=2) Shift - 2 - 2 EXE if you see "5", then it is correct. If not, then maybe I am not able to help, sorry
sorry I am not knowledgeable enough to answer you this question. I have researched a bit on it, but I could not find relevant information. sorry for that.
is your calculator the model? If so, you can press "shift + comma" to get semicolon. of course normal multiplication is fine. this video only teaches the shortcut way.
Hello your video is very helpful:) Can you teach how to use the calculator to find the individual mean and SD of each X and Y at the same time(not the group one) Thanks a lot!! Also how to find the r, a and b in the line function :)
Thanks. For your question, I am actually not very sure. Do you mean regression? See whether this program (in Chinese) helps: webcal.freetzi.com/casio.fx-50FH/regression_var.htm
I do not have the model of fx-991es plus, so I may not help you in this. I find a related video for fx-991es plus. See if it helps. th-cam.com/video/0M3dBRQtNH8/w-d-xo.html

Thank you so much you saved me from my exam
Thank you so much to share with us!
Thanks, what is sx next to SD?
that's "Sample standard deviation".
calculated by
sqrt((sum of all "square of difference") / (n-1))

shift-2 "3" (sx) gives you the sample one
why when i want to check the numbers of data and is 4instead of 66
did you use Shift - 1 - 3 to check the number of data?
I love u so muchhhhhh. great explanation^^
thanks! glad that it helps~
That is helpful, thank you.
May I ask why nothing happened when I pressed 10 and then M+ despite that I have done all the steps you mentioned before it? ( I didn’t press shift 9 3 and the model of my calculator is the same as yours)
did you enter the "SD" mode yet? (Press Mode "4" to enter the mode)
@@chericiu yes I did
@@HWei-ju8ut oops then I have no idea... You may try again exactly these procedures:

@@chericiu ok thanks 🙏
Plz let me know how to find a group of scattered number in ascending order..my calci is 991es plus
sorry I am not knowledgeable enough to answer you this question. I have researched a bit on it, but I could not find relevant information. sorry for that.
Nice video, thank you so much.
Thank You so much!!!
But just one reminder.
That's "Data" not "Dater"
not speaking English well 🙈 nvm
2025dse still watching😁
It’s nice and clear thanks
I don't have semicolon in my calculator, can i use normal multiplication

Thank You!! How to change between population and sample mean in the calculator?
the one from the calculator is the sample mean.
this is also the estimate of population mean.
very helpful，thank you
You are a legand... please become a teacher
thank you. I'm indeed a teacher in Hong Kong haha
