It's 1:09am, In South Africa, Cape Town. It's a day before my birthday, I'm doing a Stats assignment for my postgraduate diploma and you are the only person who perfectly explained this to me! Thank you!
Brilliant - you have made the process of establishing Q-Q plots rather simple...I was scratching my head and only 24hrs until my assessment was due. Fingers Crossed I am on the right track. Thanks Again
I am new to this topic can you please explain me why you calculate formula {i-0.5)/n ? Can you please help me ... and one more question what is difference between {i-0.5)/n and standardized x value ..?
Helpful. But standard Normal has SD=1, while the sample may not. Shouldn't you calculate the standard deviation of the sample before comparing to a standard normal? this topic is sending me mad...
what do you do, open to anyone, if you have many mutiple/repeated data values in the original data set using this method, the qq plot formed looked odd and didn't appear to follow a straight line

Hello. To everyone I recommend sorting values first! The video confused me untill 8:20, when he finally sorted the data...
Thank you for posting this Jalayer, much faster in R, but useful to know how to do this in excel. Many thanks!

Hello Josh,
My name is Hillary Clinton and my husband is a sex offender.
Kind Regards,

that was awesome, thank you very much. how about t.distribution?
What software do you use to draw on screen???
Why is i-.5/count in the second columns? DId not understand? Please explain.
In this case we standardized the x scale were as in the Z score case we standerdised the x Vals
Jalayer Academy Shouldn't we have x values on x-axis and z-values on y-axis? Am i wrong?
to show the values are in the normal distribution curve, z is always on horizontal axis. Thats how a curve would be made.
how did you get the value of x?😅
Why is the probability equal to (i - 0.5) / n ?
Chiyui Leong i'd like to know it too, but i think it's just a way to divide the values from 0 to 1 with equal intervals
I am guessing that the confidence level is 95% and the 0.5 represents the a value
Helped me, thanks.
how he select the pencil in excel and draw
Buen video, pero no tengo la opcion en excel de "Norm.s.inv". Como podria solucionarlo?
en español la funcion es: =INV.NORM.ESTAND(probabilidad)
thank you
This dude sounds like David Blaine
why is my probability more than 1. :C
arrange the data first
