What does the function =SUMPRODUCT() do?

• A. Returns the sum of products of corresponding components in arrays
• B. Calculates the average of a set of values
• C. Counts the number of non-empty cells in a range
• D. Generates a random number within a specified range

Answer: (A)

The function =SUMPRODUCT() is designed to return the sum of products of corresponding components in the provided arrays. When using this function, you input two or more arrays, and it multiplies the elements at corresponding positions and then sums up these multiplied values. This can be particularly useful for weighted calculations where each element contributes to the total in a specified proportion. For example, if you have an array of quantities and an array of prices, using SUMPRODUCT can give you the total cost by multiplying each quantity by its corresponding price and summing the results. In contrast, the other options represent different functions and purposes that do not accurately describe what SUMPRODUCT does. One option refers to calculating an average, which is not related to what SUMPRODUCT handles. Another option mentions counting non-empty cells, which is the domain of the COUNTA function. Lastly, generating random numbers falls under the random number functions such as RAND or RANDBETWEEN, which have no connection to the product-sum functionality of SUMPRODUCT. Thus, the correct answer aligns perfectly with the unique, specific operation performed by the SUMPRODUCT function in Excel.
