The SUMXMY2 function returns the sum of the squares of the differences in two arrays.
Formula:
=SUMXMY2(array_x, array_y)
Explanations:
1. Array_x is required which is the first data array.
2. Array_y is required, which is the second data array.
Cautions:
Array_x and array_y will have the same number of values, otherwise, the function returns the #N/A error.
Example: What is the sum of the squares of differences in Column A and Column B?
=SUMXMY2(A2:A11,B2:B11)
The function is 490.
You can also break down to use the traditional method to check the accuracy. The result is also 490.
