8 years later, this absolutely saved my life on my university lab report, huge props to you!

[nmy]

This changed my life on a spiritual level. Thank you :')

[TurrettiniPizza]

You know it's an old video when they ask you to share it on Google+. RIP.

[Pandaheartt]

THANK YOU SO MUCH! This is way more helpful than my useless TA.

Thank you for actually sharing a tutorial in R that actually leaves us more informed than confused!

[angelgurgutov]

Sir, thank you, that was very well described! However, the links provided are damaged, I could not access them.

[chrohm]

you are a fantastic presenter, provide great voice and audio quality...thanks

[WahranRai]

Well explained.
2:53 Line 7 : cbind is not necessary,
data.frame(group1, group2, group3) is sufficient

I did the exact same thing as the video and IaA get the error : Error in eval(predvars, data, env) : object 'values' not found

[zapy]

Thank you so much for this video. Your visual description is great for understanding.
Is there a way to conduct this test without stacking the data?

[ely]

I have no words to thank you, you did for me what books and other tutorials could not, great job!!!

[mola]

Your explanation is brilliant. can you please post how to calculate Two Way ANOVA using R? 

[gregmartin]

Thanks! This was an extremely useful video. Will share for sure!!!

[undefinedvaccum]

Yeah i hoped for that kind of explanation of how to use R, thank you

[larzdawson]

Why does mine say “values not found”?? I would appreciate any insights😊

[jooliworld]

Is this for one way anova or two way anova?

[Sisco-]

thank you so much!
but for fresh starting from data entry up to final interpretation is vital to reduce confussion

[jastootie]

Thank you!! But why does the data have to be stacked? Is there a way to simply import a .csv file of my data table, and then run the aov function? Or do I have to manually create vectors, combine the vectors into a data frame, and then stack the data frame? The whole process seems long for something as simple as a one-way ANOVA, no?

[yangwang]

Hi, thanks for your video, it's very clear! I have a question about the sample size, so in your video the sample size for each group is 4, what if the sample size is only 3, and have thousands of comparisons, is it still appropriate to use anova? If I use t test to compare 3 different groups, is there any difference with t test? Thank you! Any reply will be highly appreciated!

[prodfife]

wow, never knew it would be as simple as creating groups and stacking them, seems way easier than trying to finesse factor levels into my existing datasets.

great video!
