The SUMXMY2 function returns the sum of the squares of the differences in two arrays.
1. Array_x is required which is the first data array.
2. Array_y is required, which is the second data array.
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?
The function is 490.
You can also break down to use the traditional method to check the accuracy. The result is also 490.
