In this article, we will guide you through the process of calculating a weighted average in Excel. Weighted averages are useful when you want to assign different weights to data points before taking an average. This technique is commonly used in finance, statistics, and other fields where data points have varying significance.

Here are the steps to calculate a weighted average in Excel:

1. Prepare your data

For this example, let’s consider that we have the following data set:

– Test scores: 72, 90, 85

– Weights (percentage): 0.3, 0.5, 0.2 (30%, 50%, 20%)

First, create a table in Excel with the following column headings: Test Scores (column A), Weights (column B).

| A | B

1 | Test Scores | Weights

2 | 72 | 0.3

3 | 90 | 0.5

4 | 85 | 0.2

2. Multiply test scores by their corresponding weights

In column C, multiply the test scores of column A with their corresponding weights in column B.

| C

1 | Weighted Scores

2 |=A2*B2

3 |=A3*B3

4 |=A4*B4

After entering these formulas for each test score, you should see the weighted scores as follows:

| A | B | C

1 | Test Scores | Weights| Weighted Scores

2 | 72 | 0.3 | 21.6

3 | 90 }}”>{{28}}”
