The SUMX2PY2 function in Google Sheets is a powerful tool that allows users to calculate a specific mathematical sum involving the squares of two different sets of values. By applying this function, users can efficiently perform data analysis that requires summing the products of squared numbers from two arrays, making it particularly useful in statistical computations and financial modeling.

Syntax

SUMX2PY2(array_x, array_y)

• array_x: This is the first array of numbers whose squares will be summed.
• array_y: This is the second array of numbers whose squares will be summed.

Example #1

SUMX2PY2(A1:A3, B1:B3)

This function call computes the sum of the squares of the values in the range A1:A3 and the range B1:B3. If A1=2, A2=3, A3=4 and B1=1, B2=1, B3=2, the result will be 42.

Example #2

SUMX2PY2({1, 2, 3}, {4, 5, 6})

This function call sums the squares of the values from the two arrays, resulting in (1^2 + 2^2 + 3^2) + (4^2 + 5^2 + 6^2), which yields 91.

Example #3

SUMX2PY2({-1, -2}, {3, 4})

Here, the function calculates the sum of the squares of -1 and -2 from the first array, along with 3 and 4 from the second array. The result will be 30, since (-1^2 + -2^2) + (3^2 + 4^2) equals 30.

Error handling

• N/A: This error occurs when the arrays are of different lengths, making it impossible to pair corresponding elements.
• VALUE: This indicates that one or both of the specified arrays contain non-numeric values, which cannot be squared.
• REF: This error signifies that a referenced cell in the provided ranges is invalid, possibly due to deletion or improper range definition.

Conclusion

In summary, the SUMX2PY2 function serves as an essential tool for users needing to perform calculations involving the squared values of two arrays. Its efficiency in dealing with numerical data analysis enhances the capabilities of Google Sheets, making it invaluable for various quantitative tasks.
