CorrelLab
How strongly — and in which direction — two variables move together.
Pearson's r ranges from −1 (perfect inverse relationship) to +1 (perfect direct relationship), with 0 meaning no linear relationship at all — it only captures linear association, so a strong curved relationship can still score near zero.
A high correlation tells you two variables move together, not that one causes the other — ice cream sales and drowning rates correlate strongly because both rise in summer heat, not because one causes the other.
