Correlation

Measure of the strength and direction of association between two variables; correlation alone does not prove causation.

Examples

01The analyst finds a strong correlation (r = 0.82) between room humidity and paint defects over 60 days.
02The correlation is checked by paint booth and by colour, because a combined view could hide or create a false link.
03Since correlation does not prove cause, the team runs a controlled test with a dehumidifier before investing.
