You man saved my life!! thats awesome
Very helpful. Thank you so much.
thankyou buddy! great help
So helpful.Thank you
omg this is so helpful! i was calculating the standard deviation manually for 29 elements and it was taking up so much time!
How do you calculate s^?
you're amazing!
Thank you so much
can i have a shoutout during class?
tku mr, -dianopangvictor dan kawan kawan
thank you
Very helpful, thank you!
Glad it was helpful!
Thanks!
Thank you so much 🥰
thank you you have saved me

What do I do when the value of N is very large, say 500 ? The answers do not match certain approximations.
On the discriminantquestion why don’t you not use the 3 in 3-c
Hi, the 3 has been used, but for space and likely time saving, I completed the steps in one. The breakdown would be: 16 -8(c-3) = 0 16 - 24 + 8c = 0 -8+8c = 0 c = 1
In case you need this: type_A_uncertainty = st_dev(X) / sqrt(n) Being n the number of samples.
is there a way to see the Quartiles, percentiles & Deciles in this calculator ?
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.
hey this is very POWERFUL VIDEOS, i always learn a lot, which device are you using, to make such video, is iT SAMSUNG GALAXY, MICROSOFT PRO, OR IPAD PRO, or which device ? thanks very much, is it ZOOM or OBS ? thanks very muh , and keep on doing excellent works , youre smart person, i been following you for a more than a year now

logs needs to learn a few bit tricks from Mr. Rayner, if it wants to be seen in a good way.
Maths needs to invent even more numerical methods to find inghe ultimate solution to the infectious spread of positivity from Mr. Rayner itself.
Unfortunately, even math can't contradict Mr Rayner's charm by proof.
Unfortunately, Mr Rayner isn't placed in the average section of normal distribution because he's further down in the top 1% of the distribution amongst legends.
the derivative for the solution of maths is Mr.Rayner himself.
The man, the myth, the legend, the one and only Mr Benjamin Rayner.
Thanks
I think that seven randomly selected students is a sample (the size of the sample is smaller than populations). The population would be all the students who took the test. So, i got a little confused when you said tha "sx" is a sample population. What does that mean? And if you meant sx is the standard deviation of the sample, then shouldnt we use this instead of σx ?
Hi, you would use sx for a sample from the overall population and σx to find the actual standard deviation given the data for the entire population. Effectively, sx is an estimate for the s.d when we only have a sample.

Question - what settings would you have to change if you entered your raw data into list 1 and it's displaying an error
It says "dimension error".
@@ariisair as far as mine calculator, it only says dimension error when you try to hit the F1='1-var" button before you list your raw data. I put my data first, i press the F1 and see my results.
@@ariisair on 6:13 he explains
Very well explained sir
exactly what I needed, short and to the point with clear explanation. Many thanks !!
that's why we call him the king of maths.
thanks
Thanks a lot 😁😁
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.
Thank you sir
Thanku Sir
Sir It's really helpful
Thank you this is going to help me a lot in my entrance exam.
Thank you
You're welcome :)
