Hello Can you explain me please about the following explanation: Is there a connection between the number of employee subtractions and his motivation (I will attach a picture here)? x = the number of employee subtractions y = motivation About two left columns in the table  it's just a calculation. 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!

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
