CORREL
Returns the Pearson correlation coefficient of two sets of data.
Syntax:
CORREL(x; y)
- where x and y are ranges or arrays containing the two sets of data.
- Any text or empty entries are ignored.
- CORREL calculates:
- where
are the averages of x,y.
- Advanced topic:
- The parameters x and y are always evaluated as array formulas.
Example:
CORREL(A1:A30; B1:B30)
- returns the Pearson correlation coefficient for the two sets of data in A1:A30 and B1:B30.

Issues:
- CORREL is identical to PEARSON.
