Kendall's Tau [Easily explained]
Kendall's tau is a correlation coefficient and is therefore a measure of the relationship between two variables.
But what is the difference between the Pearson correlation and the Spearman rank correlation? In contrast to the Pearson correlation, the Kendall's rank correlation is a non-parametric test procedure. For the calculation of Kendall's Tau, the data does not have to be normally distributed and the two variables only have to have an ordinal scale level. Kendall's Tau is very similar to Spearman's rank correlation coefficient. However, Kendall's Tau should be preferred over Spearman's correlation when there is very little data with many rank ties!

Hi thanks for your feedback! I will have a look at it! Regerds, Mathias
i have two variables, one being age and the other being time spent reading news papers, can i use kendall's tau? the time-variable i have both in scale version (time spent reading in minutes) and as ordinal (never, sometimes, often etc) because my data is not normally distributed and showed heteroscedasticity (i wanted to use linear regression)
thanx ma,am
Very helpful video - and I echo the point in the previous comment - would like to know the difference between Tau-a, Tau-b etc. 👍🙏

You're welcome!
but what if there are equal ranks? how do you calculate then?
What if the reference column wasn't sorted?

damn, chat gpt ruined my knowledge i hope yu make more video
good for Miu
Thank you German People!
