Perform ANOVA Post-Hoc Tests (Bonferroni Correction) In Excel

[@malwalsabino519]

Now my understanding of ANOVA in general and single factors including post ad-hoc is complete. Thank you so much for the clear interpretation.

I just stumbled upon this channel. I really appreciate the clarity of your explanations. These are topics that can easily be made obscure by disorganized explanations. You keep every simple, accurate and organized. Thank you for that

Thanks mate. Appreciate that! Happy New Year!

Excellent video! Not only do you show how to do it simply, but now I understand HOW it works and why. Thank you!

I am amazed at your simple yet logical conclusions drawn using simple tools available in EXCEL. Thanks again. I appreciate your teaching skills

I appreciate your very helpful and concise content! Just a few questions, though: 1. If 2 of the groups turned out to be insignificant, and only 1 is significant, is the null hypotheses then considered? If so, are there any statistical tests to be applied next? 2. In the last slide, why is it that you used p

[@sidsavvy7936]

You are awesome ❤️

[@john-patricksharpe551]

Very useful and clear video ! Thank you :) to conclude, is it possible to say that Region 1 and 2 can be grouped under the letter A and the Region 3 under the letter B ? That way it would be possible to make a graph with the variable region on the x axis, the measurement on the y axis, add the mean value on an histogram shape and finaly add the letter A or B for each variable region ? This is the kind of graph that comes out when making an ANOVA with XLSTAT software.

[@DILEEPKUMARKORAM]

Hi I didn't understand how you came to the conclusion. Is it based on the Mean?

[@pawanboharupi5627]

Awesome 😎

[@lichen938]

IT'S SO USEFUL, THANK YOU

[@Jony625]

Hi good day. This is useful. However why do you have p

[@maths_statshub5243]

I believe this is because the 0.001 is the alpha level used in testing rhe ANOVA and not the Bonferroni

[@vinothkumar-bb7zi]

i appreciate

[@srinithisrinivasan8858]

And also I have one doubt , I am having standard and test samples at 6 different concentrations I want to do statistical analysis which method can I do if one-way ANOVA means how to clearly do that can you please explain..

[@noname-zp8sn]

isn't it just like T test in general? why it can be used as one way ANOVA post hoc?

hi, really useful but i keep getting value with 'e', like 4.37477E-07? i understand it means to the power of. is there an easy way of expressing this number please

Thanks Simon. Sure. Right-click on the cell and select Format Cells. Change the category to Number. Then increase the decimal places to whatever is best for you. Thanks!

@@StevenBradburn ok thanks, just tried it and i get 0.000000000000000000000000000000, could only go 30 decimal places but when i select the cell is show 1.02902692632603E-100. Is the number just to small?

What a video. Thank you.

[@minjang4288]

at 3:38, what if one-way ANOVA test give you the p value greater than 0.05 (in my case I got 0.08 with my sample group)? How do you procedure Bonferroni correction? what is the alpha value then? can you just do same? Please let me know.... I desperately need your help

[@safasafa23]

I don't know if my answer now will help you or not but the post hoc test are realizable only when one-way ANOVA test give you the p-value less than 0.05

[@philippmaass4796]

Thanks for the video! Why is the significance of the final result p

[@kamilwaszynski2372]

Alpha is just the theoretical value statisticians have chosen to compare to our actual p-value. If our p-value is less than .05, then we can reject the null hypothesis. This just means that we must be at least 95% certain that the data obtained is due to the independent variable, and not random chance.

[@szy0931]

it is because of Bonferroni adjustment. The new p value = 0.05/n.

[@cococnk388]

Since we are doing three pairwise test, for each test we do compound alpha = probability of making a type I error = 1 - (0,95)^3 there is a high probability of having the test falsely significant, so we divide alpha by our number of pairwise tests.

[@mohammedmanik1408]

One of the best videos I have ever seen. Thank you, Mr. Steven

[@BobbeeSingh]

I was following everything until the very end starting at 7:15 where everything was to come together and I didn't get how region 3 was significant. How did we reach that conclusion?

[@williamstevens2382]

I don't know if this is still useful to you but: Region 3 is significantly different because the p-value is smaller than the post-hoc-test alpha value when comparing against both region 1 and region 2.

You made my day! I was upset because I didn't know how to comment my data and you gave me a perfect way to do that! Thank you again
