The formula for the correlation hand calculations is:
r = [(nΣxy) – (ΣxΣy)] / √[(nΣx²) – (Σx)²][(nΣy²) – (Σy)²]
| Dataset | Correlation Coefficient |
|---|---|
| Dataset 1 | 0.85 |
| Dataset 2 | 0.62 |
- Always use the correct formula for your specific use case.
- Understand the limitations of correlation coefficients.
What is the range of the correlation coefficient?
