How do you calculate coefficient correlation?

Correlation Co-efficient Formula Here is the correlation co-efficient formula used by this calculator Correlation(r) = NΣXY - (ΣX)(ΣY) / Sqrt([NΣX 2 - (ΣX) 2 ][NΣY2 - (ΣY) 2 ])

What does coefficient of correlation mean?

A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between variables. The correlation coefficient is usually represented by the letter “ r “. The number portion of the correlation coefficient indicates the strength of the relationship.

How do you find the correlation coefficient on a calculator?
