Hey. Love your video. It helped me a lot. Also, on the last portion of your video (32:54), you made an error when selecting the values that were within one standard deviation of the mean. The lower boundary was 335,89, not 338.89. The correct percentage is 85%, from my calculations.
Hi can l pls enquire abt the last example, um when calculating the std deviation right?..i thought std deviation is given to us in the statement wich is 2.74...
Sir why are you using a Sigma sign to express your standard deviation while you expressed your mean as a X-bar... because the X-bar correspond with the small letter (s) as an expression of standard deviation and Muon sign is the that is supposed to be expressed as a Sigma sign?🤷♂
Hi sir On the last question looking at the learners above u looked at class A but looking at learners below u looked from class A and B I don't understand why not classB on can u plz explain it for me
Hello SIRRR.....I think u made a mistake for 2.3 because it was supposed to be the values between 336---341...plz can u just check...It is towards the end of the video

Please show me how you got that .... cause also from him i didnt get that ...
Do we count from 335 -341?
@@nomandlovu638 yes
It's 75%
@@nomandlovu638 no specifically from 335,89 - 341.31 so if a number is 335 exactly it doesn't count
Malumeeeeee....Malumeeeee..

It’s coming…

You’re welcome
Sir I think you made an mistake on last example when you calculate the standard deviation of a below mean the answer should be 335.89
Thank you for correcting me
Yha I also saw that therefore I think that the correct answer is 18/20*100 which gives us 90%
Yeah he made a mistake n I think the final answer is 15over20×100=75%

Hi Mr Nkosi ....i dont understand the standard deviation formula i need some clarity on that ...
Hi sir
On the last question looking at the learners above u looked at class A but looking at learners below u looked from class A and B I don't understand why not classB on can u plz explain it for me
Forever grateful Sir :)
Thank you 😊
❤️ Definitely
May you please avoid just giving us the standard deviation formula and actually substitute that would be highly appreciated ❤🙏🏾
Do you think it's advisable for a grade 11 learner to actually watch these
Yes… Actually it’s grade 11 content.
Strongly so
Hi sir , I think you made a mistake . Mean on Class B is supposed to be 71.6 % according to my calculations. Please kindly check that one out 😁
Sir you mad a mistake, mean for class A is 72 and mean for class B is 71.4
Thank you for pointinh that out
Sir is this the last chapter in Statistics
I’ll just do one last video on Histograms but essentially that’s it
@@MlungisiNkosi Oh okay
Thank you so much sir . May God bless you😊👍❤
