What is this post-hoc test called? Is it based on Wilcoxin's signed rank test?

@@rohithvenkatakrishnan7236 Yes! It is based on wilcoxon signed ranked test but for three set of scores. Although there are some negotiation about this post hoc test for friedman test. If you have any doubts about the best post hoc test for your data you can check this link:

Hi... This is a great video. I would to like to know more about checking the assumptions of anova for a classification problem (feature selection in python). Suppose I have 7 features how should I check the normality. Can you kindly explain it (qq plot, histogram, levene)
@statisticiansworld8912 Ай бұрын
Hi! You only need to check the normality assumption for your Target variable or 'y' variable using q-q plot. If it didn't met you should get the log() function of your target variable, then draw the q-q plot again. Levene's test is for checking the equality of variances across groups for one independent variable or feature that you are interested in.

P value is calculated on median value or mean value?
@statisticiansworld8912 10 ай бұрын
it is calculated on mean value and we can do that when our data is "not" normally distributed.

Shapiro wilk it isn't valid for test of normality it is better to consider on skewness and kurtosis and also seeing on data distribution by drawing histogram chart. Thank you
@statisticiansworld8912 Жыл бұрын
Yes this is true! it is sometimes misleading or waste of time! Actually the best way and better to say the easiest way to check out the normality assumption is using Q-Q plot (as we did) or the histogram chart. Thank you so much for your comment!
