Simply having an Excel spreadsheet program installed on any of our devices, be it a desktop or a laptop, is an advantage for us, as long as we know how best to use it. Because in it we can perform an infinite number of operations, among which we can mention the calculation of the weighted average.
Excel is a very versatile tool that helps us perform many tasks and has an infinite number of functions to offer. Among them are: creating many types of charts, issuing invoices, keeping records and organizing various data, easy mathematical operations on the entered data, among we can mention data summation, among many applications for which we can assign it.
It should also be mentioned that this program allows us to work or share files with several people online and the fact is that sometimes teamwork is better than individual work, therefore it is the convenience that the program gives us, It’s very important.
Now, in this article, we will show you how to use Excel’s SUMPRODUCT and SUM functions individually, and how to combine both to calculate some problems.
The weighted average is an average that takes into account the importance or weight of each value. A good example would be the calculation of a student’s final grade based on his or her performance on various tasks and tests.
this is usually an individual assignment. They do not count as much for the final grade as for the final exam, as quizzes, tests and final exams will have different weights.
this weighted average is computed as the sum of all values multiplied by their weights divided by the sum of all weights.
For its part, a weighted average can be associated with a measure type that is able to calculate a weight with different values that can be calculated.
Example SUMPRODUCT and SUM
For our example, let’s take a look at the test results and student tests. There are six quizzes with 5% of the total mark each, two exams of 20% of the total mark and the final exam with 30% of the total mark.
The student’s final grade will be a weighted average and we will use the SUMPRODUCT and SUM functions to calculate this. As you can see in the table below, we have already assigned relative weights to each test and exam in column D.
Step one: calculate the SUMPRODUCT
First, let’s see how the SUM PRODUCT function works. Start by selecting the cell where you want the result to appear (in our example, this is cell D13).
Next, go to the “Formulas” menu, select the “Math and Trig” drop-down menu, scroll down and click on the “SUMPRODUCT” function.
- The “Function Arguments” window appears.
- In the “Array1” field, select the student results.
- Here we select all cells with actual results in column C.
- Then use the “Array2” field to select the weight of the tests and exams.
- For us, they are in column D.
- Click “OK” when finished.
- The SUMPRODUCT function will multiply each result by the corresponding weight.
- Then it will return the sum of all these products.
Step two: calculate the SUM
- Now let’s see how the SUM function works.
- Select the cell where you want the results to appear (in our example, this is cell D14).
- Then go to the “formulas” menu.
- Select the “Math and Trigonometry” drop-down menu.
- Scroll down and click on the “SUM” function.
- This “ function arguments “.
- Select all scales in the “number 1” field.
- Click “accept”.
- The SUM function will add all the values together
Step three: Combine SUMPRODUCT and SUM
But now we can combine both functions to determine the student’s final grade on the basis of his results and the weight of each result.
- Select the cell where the weighted average should go (for us, this is cell D15).
- Then type the following formula in the function bar.
= PRODUCT SUM (C3: C11, D3: D11) / SUM (D3: D11)
- After typing the formula, press “enter” to see the weighted average.
