How to calculate weighted average in excel

Answer:
Calculating weighted average in Excel involves multiplying each value by its corresponding weight, summing up the products, and then dividing by the total weight. Here’s a step-by-step guide on how to do it:

  1. Gather the data: First, you will need to have the values and their corresponding weights ready in your Excel spreadsheet. For example, you may have a column with test scores and another column with the weights of each test.

  2. Multiply each value by its weight: In a new column, multiply each value by its corresponding weight. For example, if the test scores are in column A and the weights are in column B, you would enter the formula “=A1*B1” in cell C1, and then drag the formula down for the rest of the values.

  3. Sum up the products: In a new cell, use the SUM function to add up all the products. For example, if the products are in column C, you would enter the formula “=SUM(C1:C5)” to calculate the sum of the products.

  4. Calculate the total weight: In another cell, calculate the total weight by using the SUM function on the weight column. For example, if the weights are in column B, you would enter the formula “=SUM(B1:B5)” to calculate the total weight.

  5. Calculate the weighted average: Lastly, divide the sum of the products (step 3) by the total weight (step 4) to calculate the weighted average. For example, if the sum of the products is in cell D1 and the total weight is in cell E1, you would enter the formula “=D1/E1” to calculate the weighted average.

By following these steps, you can easily calculate the weighted average of a set of values in Excel.
