Your video was a HUGE help! Until now, I was clumsily trying to run ANOVA on website calculators, which took forever sometimes. This is so fast and easy.
Great video. I was able to help my daughter - a medicine student- with one of her lab reports because your explanation was pretty clear. Thank you very much and regards from Costa Rica. Keep up the good work !!!
I am also confused about if the F critical is higher etc...what it means etc... however what I can tell you is that null hypothesis for ANOVA is : the three groups are equal. When your p-value is smaller than 0.05 like in this case p
@Aelfredus26 reject H0 if significant (smaller 5%), this means there are treatment effects between the different groups. thats the same as: reject if you calculated F is bigger than the theoretical (F crit) at a alpha 5%. i dont know what p-value means, something with the confidence, so yea sort of the probability of you being wrong (not super duper sure if you can say it like that)
Hi there, thanks for the video I got most of it but got confused as well.. if F value is greater than f-critical, should we be ACCEPTING the null hypothesis or REJECTING it?? in the mean time if pvalue is greater than Alpha, what should we be doing?? An answer would help towards my desertation.
Thank you. That was excellent! Continuing on from your teaching, you said that an ANOVA here simply tells you that there is 'something going on'. Following on, could one then do simple T-tests comparing the 3 groups?
Someone help me. So, when the P-value is smaller than the alpha it means that we accept H1 and reject H0, just like when F is bigger than F crit? Btw, what does the P-value means? It seems to be the probability of something.
A quick and simple, but erroneously says difference in the means. Whereas, actually the ANOVA looks at the differences in the Variances of the groups under test. Secondly, you may like to give little more clear reason as why you selected 1-Way ANOVA? Overall, nice effort.
I am having problems with ANOVA in Excel. I'm getting the error "there are non-numeric entries in the data". I believe it is because the groups are not of the same size. Is this a problem in Excel? I know that other programs like SPSS can work around it
I have a question here... can we apply this on different number of population? for example group a) 100 people group b) 145 people do we need to equalize the population first? thank you it is a good video by the way!
noxth i just tried with 3 groups (4078 people, 4149 people and 4219 people) and my variance within groups was immensely larger than the variance between groups -.-
Thanks for sharing, but I don't think your video is good enough. You just tell us the result, that we can see it but still not explain it yet. What F, what F critical? What conclusion do we have if F > F critical... etc?

Really nice,mam.Thanks a lot from India.
all of your excel statistical tutorials are excellent! you really make is very simple.
Great video. I was able to help my daughter - a medicine student- with one of her lab reports because your explanation was pretty clear. Thank you very much and regards from Costa Rica. Keep up the good work !!!
Thanks a lot! really helped me out for my system design exam :) !
Thank you so much. Clearest explanation I've found.
God bless and thank you for this wonderful explanation.. have been breaking my head manually for days.
Great tutorial! Thank you.
Saved my life, thanks!
Thank you very much for posting this. It worked and that feels great!!!
thank you thank you thank you!!!! my homework is done now thanks to you! really thank you very very much :D
Brilliant tutorial. Thank you.
Very well explained: simple and useful!
Really awesome tutorial!
Thank you
Short and to the point. Great demonstration ^_^
Very useful! Thank you.
Thank you! So helpful!
Thanks for uploading! I was a little stressed out because SPSS won't work on my laptop. I'll use good old Excel instead.
Thank you so much! And by the way, I really like your voice. Its so relaxing.
you are a lifesaver. if ever u come to taiwan, let me treat u to dinner!
Oooooh yes! You have just saved a life!
Excellent video keep doing what your doing, gave me everything i needed!!!!
Thank you so much
Thank you soo much mam ...
Short and powerfull. Thanks!
Perfect.Iranians are the best teachers :)
wonderful, thanks for help

Nice Persian Accent! And of course nice job!
@Aelfredus26 reject H0 if significant (smaller 5%), this means there are treatment effects between the different groups. thats the same as: reject if you calculated F is bigger than the theoretical (F crit) at a alpha 5%. i dont know what p-value means, something with the confidence, so yea sort of the probability of you being wrong (not super duper sure if you can say it like that)
Very good!
very clear tutorial with a helpful explanation!
@Aelfredus26 It's the probability, that the population mean of all three groups are equal.
Good job, GMU!
very very helpful
Good information madam
The lesson was really good
u saved my lifeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
What is the further test that we can do to determine whether is there any significant difference between each group of data?
thank you sooooooo much :)
thank you so much !
this was helpful :) thanks!
thanks , that helps
Hi there, thanks for the video I got most of it but got confused as well.. if F value is greater than f-critical, should we be ACCEPTING the null hypothesis or REJECTING it?? in the mean time if pvalue is greater than Alpha, what should we be doing??
An answer would help towards my desertation.
Thank you very much :D
Thank you so much!
Did you check if you accidentally included the label range also? Maybe that is why.
Thank you. That was excellent! Continuing on from your teaching, you said that an ANOVA here simply tells you that there is 'something going on'.
Following on, could one then do simple T-tests comparing the 3 groups?
coldflame333 yes that are called post hoc tests
Thanks!
nice!
thank u!!!
if nid do further anlaysis to determine the diff, can we use t test?
F0 > F-critical reject. if pvalue < level of significance reject. Else there is not enough evidence to reject H0.
WONDERFUL...CAN U PROVIDE ME MULTI WAY ANOVA??
Someone help me. So, when the P-value is smaller than the alpha it means that we accept H1 and reject H0, just like when F is bigger than F crit?
Btw, what does the P-value means? It seems to be the probability of something.
A quick and simple, but erroneously says difference in the means. Whereas, actually the ANOVA looks at the differences in the Variances of the groups under test. Secondly, you may like to give little more clear reason as why you selected 1-Way ANOVA? Overall, nice effort.
Is it related to moderation analysis?
thank u
hi, how to put an output in the box??
I am having problems with ANOVA in Excel. I'm getting the error "there are non-numeric entries in the data". I believe it is because the groups are not of the same size. Is this a problem in Excel? I know that other programs like SPSS can work around it
Very Nice. Iranian are the best :)
Hi! Can you conduct the same method if solely using 2 groups rather than 3?
sure but it would be the same as conducting a t-test
Madam kindly guide me regarding interpretation with results retrieved
I have a question here... can we apply this on different number of population?
for example
group a) 100 people
group b) 145 people
do we need to equalize the population first?
thank you it is a good video by the way!
noxth i just tried with 3 groups (4078 people, 4149 people and 4219 people) and my variance within groups was immensely larger than the variance between groups -.-
+noxth
Yes. You can.
thanks guys!
just block my stress but i want to apply anova on ms-excel 2007
Hi, this is in Excel 97 right????
Select labels next time.
Thanks for sharing, but I don't think your video is good enough. You just tell us the result, that we can see it but still not explain it yet. What F, what F critical? What conclusion do we have if F > F critical... etc?
Easy on the mic, my ears hurt
