How do you find the relationship between two values?
How to Calculate a Correlation
- Find the mean of all the x-values.
- Find the standard deviation of all the x-values (call it sx) and the standard deviation of all the y-values (call it sy).
- For each of the n pairs (x, y) in the data set, take.
- Add up the n results from Step 3.
- Divide the sum by sx ∗ sy.
