Many thanks, Prof for this Excellent video! But I am referring to your previous video on ''t-test, anova and chi-square' to do the ANOVA of my research. I am now facing 2 issues: 1- I really understand the results because it missing the p-value, 2- I am having error message for the TukeyHSD. Bassically, I want to perform the ANOVA for the mean values for three years (i.e., 2017, 2018 and 2020). here is the command I run "abcanova %>% aov(formula = gprice ~ year , data =.) %>% TukeyHSD()" here is the error message "> abcanova %>% + aov(formula = gprice ~ year , data =.) %>% + TukeyHSD() Error in TukeyHSD.aov(.) : no factors in the fitted model In addition: Warning message: In replications(paste("~", xx), data = mf) : non-factors ignored: year" I can share the data if necessary I need your help thank you
Could you please talk about performing a paired t-test when the data is in wide format i.e. the intervention values are in one column and post-intervention in another?

Hello sir, Sir can you please recommend me a good UA-cam channel from Where I can learn Python from Basics to advance level
Excellent explanation, Greg. Love your simple and precise approach.
Exactly what I need to do tomorrow in my dataset thanks!!!! like always u r the best !!!!!
Happy to help! You got this, Karen! 😉
Excellent video! I really love this channel. It would be so great if you could do some time series videos in the future.
That's a great idea! Thanks for your feedback!

here is the command I run
"abcanova %>%
aov(formula = gprice ~ year , data =.) %>%
TukeyHSD()"
here is the error message
"> abcanova %>%
+ aov(formula = gprice ~ year , data =.) %>%
+ TukeyHSD()
Error in TukeyHSD.aov(.) : no factors in the fitted model
In addition: Warning message:
In replications(paste("~", xx), data = mf) : non-factors ignored: year"
I can share the data if necessary
I need your help thank you
really excellent video.
please how do you perform a paired t. test when the data is not the same length?

I am very grateful for your effort you make everything easy peasy lemon squeezy as you say 🤣🤣🤣🤣🤣thank you very much
0:43 fav part
ah - thanks for letting me know.. I didn't know that people had favorite parts.
Greg, have used the tiny model infer package for hypothesis testing?
I've never used it - I'll check it out
@@gregmartin I think you might like it. It's basically a "grammar of hypothesis testing" that fits in well with other aspects of the tidyverse.
Hi Do you have videos on One Sample Hypothesis T-Test on a Proportion?
Thank you!
Perfect!
Thank you :)
Got u from kenya
H iMugo - say hello to others in Kenya (lovely country - I've been a few times)
@@gregmartin Your teaching are clear and simplified .
I found that two.sided had to be quoted
Thanks peter - you may be right (could be an error in the video - sorry)
good
