## What is SUMX2PY2 function in Excel?

SUMX2PY2 function is one of the Math and Trig functions in Microsoft Excel that returns the sum of the sum of squares of corresponding values in two arrays. The sum of the sum of squares is a common term in many statistical calculations.

## Syntax of SUMX2PY2 function

SUMX2PY2(array_x, array_y)

The SUMX2PY2 function syntax has the following arguments:

**Array_x:**The first array or range of values.**Array_y:**The second array or range of values.

## SUMX2PY2 formula explanation

- The arguments should be either numbers or names, arrays, or references that contain numbers.
