Dr. Grande- Your explanation in using excel for ANVOA was very helpful. This video is a great resource on when to understand the factors that are combined, and how to understand the normality with different groups. Thank you for making this clear and easy to understand.
I found out late in my collegiate career that I enjoyed statistics and research. Therefore, this was exciting for me to watch. I am interested in the more complex statistical tests that I have not had much exposure to. This has a lot of factors combined, but was very clearly explained. Thank you!
You do a great job. Best I have seen online. Many instructors talk too fast. I like your pace and thorough teaching methods. I am going to suggest Northeastern University IT class use you as a tutorial tool. Thanks!
OMG! you are the BEST!!!!!!!!!!! It's Sunday and i've been working on my project since Friday. I just needed to answer 1 more question for this first part of what my Prof assigned and you helped me soooooooooooooo much! THANK YOU!
Hello Dr. Todd, I have been trying to learn how to preform an ANOVA analisis and your videos are great, however on my data set, every time I try to follow your instructions there is a mesagge saying "input range contain non numerical data". I dont know what to do, acording to the example from the video, actually the first column is a non numerical data so I am not sure how to fix my tables. I have another question, it is posible to analize more than one treatment and more than one sample with the ANOVA - two ways with replicates?
I confused the part interpreting the P-value because of setting up the H0. Below information help you understand better if you have the same problem. Ho(Null hypothesis) for ANOVA testing is always = No differences between means and the alternative hypothesis is there is at least one differences between the means. So; Ho= U1=U2=U3 H1= Means are not equal Hope this helps.
Very nice video. Thanks a lot for posting it. Do you have anotherone explaining how the ANNOVA is performed when the variables are not independent? For example when you want to evaluate differences between two samples where results for different components are expressed as a porcentual distribution? Thank you very much in advance!
Hi, thanks for your tutorial. It is really good. I am wondering if we could do ANOVA with different sample size of each group. Let's say there are 15 samples both in your "Substance Use" group and "Depression" group, but there are 12 samples in "Trauma" group. Could we still do the two-way ANOVA with excel? Thanks!
Hi, Thank you for your tutorial ...I was wondering if we need to do the post hoc test for the result when we get the significant result in two way anova with replication...and how? Can you give some guidances using LSD or Tukey test for this..Thanks
Taking a break from Dr.Todd's analysis of crimes to Dr.Todd's analysis of variance is a breath of statistically significant fresh air.

You're welcome, thanks for watching -
Great explanation, this 12 minute long video tied together over a days worth of fragmented knowledge gained from various web pages. Thanks
Can Excel be used if sample sizes among the six groups are unequal?
Great video, thanks!
Thanks a lot, best explanation from half a dozen videos I've watched here :)
I'm glad you found the video useful - thanks for watching -
Wow great,, worth watching while learning.
Very nice presentation. I am a layman in statistics, yet, understand the things you explained. Thanks.
You're welcome, thanks for watching -
What post op test did you perform to see what the difference in score are for the columns
If I have different number of samples for each categories, how should I do ANOVA ?

I have another question, it is posible to analize more than one treatment and more than one sample with the ANOVA - two ways with replicates?
Are two-way ANOVA with replication and two-way repeated measures ANOVA two names for the same thing?
I confused the part interpreting the P-value because of setting up the H0. Below information help you understand better if you have the same problem.
Ho(Null hypothesis) for ANOVA testing is always = No differences between means and the alternative hypothesis is there is at least one differences between the means. So;
Ho= U1=U2=U3
H1= Means are not equal
Hope this helps.
So that would be a kind of mixed ANOVA, with both between-groups and within-groups factors. Am I wrong?

Really, deeply appreciate your help kind sir. Thank you!

what if we do not have same row samples?
