And then: The answer is -0.85, therefore, there is a negative connection with strong intensity. I didn't understand how and where the numbers of Rx and Ry (from the table) came from? I understood about: high=4.5 or 2=3, it's about ratings from low to high, but why these numbers? why it started from 1 in Rx and 1.5 in Ry? Thanks!

Omg, I'm really sorry but it's not Pearson, it's Spearman's rank correlation coefficient: https://en.wikipedia.org/wiki/Spearm...on_coefficient

The entire post is only about Spearman.
Sorry again, sometimes I get confused between these names (Pearson and Spearman).

Do you still need the entire problem? if yes, I will post it
