**Pearson's Correlation** - Pearson's correlation reflects the degree of linear relationship between two variables.

Pearson's correlation coefficient (r) for continuous (interval level) data ranges from -1 to +1:

Positive correlation indicates that both variables increase or decrease together, whereas negative correlation indicates that as one variable increases, so the other decreases, and vice versa.
