I believe it is impossible to observe multiple slopes in a Person correlation graph. But at least the information that no clear linear correlation between the two variables is clear. If so, the Pearson correlation is not an appropriate model to fit the correlation. You may need other models to estimate the non-linear relationship.

Hi, I realized that it seems the concept “outcome” is different from the term “output”. Taking the grandparent training project as an example, what is the “outcome’ referable?
