After this tutorial I felt dumb for not understanding this in class…this video is legendary it’s basically ANOVA in it’s simplest form
Comment from : Mervin

There is a problem the mean of means is not necessary equal to mean of the whole data unless sample size in every group is the same

But your videos are great, tommorow is my exams and youre helping a lot
Comment from : Devesh Sanil

If you take the mean of the sample means, when sample size is different, the value will be different (Weighted average) The grand mean just sums up all values divided by total number of values
Comment from : Devesh Sanil

Too repetitive and talks to much, just do and say

Comment from : Rico’s FamChan

Please when is the next video on Anova dropping?
Comment from : Michael Agyare

Great video, but you should keep apart these two characterizations of "grand mean": (1) Mean of all individuals combined and (2) Mean of the sample means (1) is always true (by definition), but (2) only coincides with (1), if all samples have the same size
Comment from : Lea Custer

Comment from : Mina Sarofem

"Grand mean is the mean of sample means" but what if sample sizes are different?
Comment from : Lucy Cai

Thank you sir
Comment from : kalsang bhutia

love, love, love your explanation you made it so easy thank you so much
Comment from : Angel Torres

But the average of sample means is not equal to the grand mean if sample sizes are not the same for all populations being compared, is it?
Comment from : Marina Afanasyeva

around time 5::27 he says that the mean of the sample means, is the mean of all the data in the samples This is correct only if the sample sizes are the same, (just as in his example), but not in general
Comment from : Uzi Paz

Thank you so much you have successfully improved my understanding of The Grand Mean! I love your teaching style and how you clearly explain what you're referring to and what it does and how it does it! This video is an absolute 'must-watch' for all students doing statistics!
Comment from : Coventry Kids

what if there a different sample size how to compute the grand mean
Comment from : Jane Sy

Hi, you are not supposed to refer to"j" as the 'jth' sample The 'i' represents the sample but the 'j' represents the observation

Dear PhD Math and Science, you explain really good Thank you
Comment from : Alvaro Romero

sorry I CAN'T MAKE SENSE
Comment from : anonymous person

What if the sample sizes are different? Is the grand mean still the mean of the sample means, or would you add all the data values and divide by the total number of readings?
Comment from : Francis Artanis

Thanks the equation has always scared me away but they are simple once you know Thanks again!
Comment from : Emo_Galaxy

Great video and explanations brbrOne comment: the mean of all the data points will only be equal to the mean of sample means if the sample size numbers are equal

What should happen if the sample sizes are different?
Comment from : Kirk Lopez

Thank you so much
Comment from : Ordinary gurl

hello sir why you divided by 30? the sample mean is always N-1 So you need to subtract the grand total by 27?
Comment from : SYED ADEEL HUSSAIN

A better question would be:br"Why is Texas letting girls get married at 13 years old"?
Comment from : Victor Drew

Your explanation seems a bit misleading: the mean of means is only equal to the mean of all the data if the samples have the same size Of course, with the formula later it‘s clear, that this is taken into account
