Association Analysis

Asteroid

General speaking, this is a statistic question, could anyone tell the differents, advantage, and disadvantages of 3 Association Analysis measures?

  1. Pearson Correlation
  2. Spearman Correlation
  3. Hoeffding's D statistic

I think there must have some reasons why Alteryx put these three together.

Here is the result from the sample workflow, one is the result of Pearson Correlation and Hoeffding's D statistic. I know the meaning about red, bule,  +, - , but what is it tell me from the result if I compare these two result?
