More resista(cid:374)t to outliers tha(cid:374) pearso(cid:374)"s r is.

Examine three aspects of relationship between categorical variable and interval-ratio variable. If sample is randomly drawn from a population, whether relationship is statistically significant. Can explore relationship between categorical variable x and interval-ratio variable y by comparing.
