To count rows in a table that meet multiple criteria, some of which depends on logical tests that work at the row-level, you can use the SUMPRODUCT function.
You have a table that contains the results of sports matches. You have four columns: home team, visiting team, home team score, visiting team score. For a given team, you want to count only matches (rows) where the team won at home. It's easy to count matches (rows) where a team was the home team, but how do you count only wins?
This is a good use of the SUMPRODUCT function, which can handle array operations (think operations that deal with ranges) natively.
The SUMPRODUCT function is programmed to handle arrays natively, without requiring Control Shift Enter. It's default behavior is to multiply corresponding elements in one or more arrays together, then sum the products. When given a single array, it returns the sum of the elements in the array.
In this example, we are using two logical expressions inside a single array argument. We could place each expression into a separate argument, but then we'd need to coerce logical TRUE FALSE values to ones and zeros with another operator.
By using the multiplication operator to multiply the two arrays together, Excel will automatically coerce logical values to ones and zeros.
After the two logical expressions are evaluated, the formula looks like this:
SUMPRODUCT is designed to work with arrays. It multiplies corresponding elements in two or more arrays and sums the resulting products. As a result, you can use SUMPRODUCT to process arrays that result from criteria being applied to a range of cells...
In the example shown, we want to count rows where the color is "blue", OR the pet is "dog". This can be done with Boolean logic and the SUMPRODUCT function like this: = SUMPRODUCT ( -- (( C5:C11 = "blue" ) + ( D5:D11 = "dog" )...
The Excel SUMPRODUCT function multiplies ranges or arrays together and returns the sum of products. This sounds boring, but SUMPRODUCT is an incredibly versatile function that can be...
