The AVERAGE.WEIGHTED function in Google Sheets is a built-in formula that calculates the weighted average of a range of cells. It takes a range of cells and a corresponding range of weights or frequencies as arguments and returns the weighted average of the values in the cell range. The AVERAGE.WEIGHTED function is commonly used to take into account the relative importance of each value in the range when calculating the average. To use the AVERAGE.WEIGHTED function, simply select the range of cells that you want to average, and then type “=AVERAGE.WEIGHTED” followed by the range of cells and the corresponding weights or frequencies in parentheses. The result will be displayed in the cell where you entered the formula.

Syntax of AVERAGE.WEIGHTED Function

The syntax of the AVERAGE.WEIGHTED function in Google Sheets is:

AVERAGE.WEIGHTED(range of cells, range of weights or frequencies)

To use the AVERAGE.WEIGHTED function, you need to specify the range of cells that you want to average, as well as the corresponding range of weights or frequencies. For example, if you want to find the weighted average of cells A1 to A10 with weights in cells B1 to B10, you would type “=AVERAGE.WEIGHTED(A1:A10, B1:B10)”. The result will be displayed in the cell where you entered the formula. You can also use the AVERAGE.WEIGHTED function to find the weighted average of a non-contiguous range of cells by specifying multiple cell ranges separated by commas. For example, “=AVERAGE.WEIGHTED(A1:A10, B1:B10, C1:C10, D1:D10)” would calculate the weighted average of the values in cells A1 to A10, B1 to B10, C1 to C10, and D1 to D10.

Examples of AVERAGE.WEIGHTED Function

Here are three examples of how you can use the AVERAGE.WEIGHTED function in Google Sheets:

1. To find the weighted average of a range of cells, select the range of cells that you want to average, and then type “=AVERAGE.WEIGHTED” followed by the range of cells and the corresponding weights or frequencies in parentheses. For example, if you want to find the weighted average of cells A1 to A10 with weights in cells B1 to B10, you would type “=AVERAGE.WEIGHTED(A1:A10, B1:B10)”.
2. To find the weighted average of a non-contiguous range of cells, specify multiple cell ranges separated by commas. For example, “=AVERAGE.WEIGHTED(A1:A10, B1:B10, C1:C10, D1:D10)” would calculate the weighted average of the values in cells A1 to A10, B1 to B10, C1 to C10, and D1 to D10.
3. To find the weighted average of a range of cells that meet certain criteria, you can use the AVERAGE.WEIGHTED function in combination with the IF function. For example, “=AVERAGE.WEIGHTED(IF(A1:A10>5, A1:A10), B1:B10)” would calculate the weighted average of the values in cells A1 to A10 that are greater than 5, using the weights in cells B1 to B10. This can be useful for analyzing and summarizing data based on certain conditions.

Use Case of AVERAGE.WEIGHTED Function

Here are a few real-life examples of how you can use the AVERAGE.WEIGHTED function in Google Sheets:

1. A teacher wants to find the weighted average test score for her class. She has a Google Sheets document with the test scores for each student in separate cells, and a corresponding range of weights representing the relative importance of each score. She can use the AVERAGE.WEIGHTED function to quickly calculate the weighted average score for the entire class by selecting the range of cells with the scores and weights and using the formula “=AVERAGE.WEIGHTED(A1:A30, B1:B30)”.
2. A sales manager wants to find the weighted average sale price for a specific product. She has a Google Sheets document with the sale price for each individual sale in separate cells, and a corresponding range of weights representing the relative importance of each sale. She can use the AVERAGE.WEIGHTED function to quickly calculate the weighted average sale price by selecting the range of cells with the prices and weights and using the formula “=AVERAGE.WEIGHTED(A1:A100, B1:B100)”.
3. A market researcher wants to find the weighted average age of survey respondents who reported a high level of satisfaction with a specific brand. She has a Google Sheets document with the survey data, including the respondents’ ages and satisfaction levels, and a corresponding range of weights representing the relative importance of each respondent. She can use the AVERAGE.WEIGHTED function in combination with the IF function to calculate the weighted average age of satisfied respondents by using the formula “=AVERAGE.WEIGHTED(IF(B1:B100=”High”, A1:A100), C1:C100)”. This allows her to analyze and summarize the data based on the satisfaction level reported by the respondents and the relative importance of each respondent.

Limitations of AVERAGE.WEIGHTED Function

One limitation of the AVERAGE.WEIGHTED function in Google Sheets is that it only works with numeric data. If you try to use the AVERAGE.WEIGHTED function on a range of cells that contains text or other non-numeric values, the function will return an error. This means that you will need to make sure that the range of cells you are using with the AVERAGE.WEIGHTED function only contains numeric data.

Another limitation of the AVERAGE.WEIGHTED function is that it does not automatically ignore empty cells or cells with errors in the specified range. This means that if there are empty cells or cells with errors in the range, the AVERAGE.WEIGHTED function will include them in the calculation, which can produce inaccurate results. To avoid this, you can use the IF and ISNUMBER functions in combination with the AVERAGE.WEIGHTED function to only include cells with numeric values in the calculation. For example, the formula “=AVERAGE.WEIGHTED(IF(ISNUMBER(A1:A100), A1:A100), B1:B100)” would calculate the weighted average of the values in cells A1 to A100 that are numbers, using the weights in cells B1 to B100, and ignore any empty cells or cells with errors in the range.

Commonly Used Functions Along With AVERAGE.WEIGHTED

Some commonly used functions that are often used in combination with the AVERAGE.WEIGHTED function in Google Sheets include the IF, SUM, and COUNT functions.

• The IF function is often used with the AVERAGE.WEIGHTED function to calculate the weighted average of a range of cells that meet certain criteria. For example, you could use the formula “=AVERAGE.WEIGHTED(IF(A1:A100>5, A1:A100), B1:B100)” to calculate the weighted average of the values in cells A1 to A100 that are greater than 5, using the weights in cells B1 to B100. This can be useful for analyzing and summarizing data based on certain conditions.
• The SUM function is often used with the AVERAGE.WEIGHTED function to calculate the total of a range of cells, in addition to the weighted average. For example, you could use the formula “=AVERAGE.WEIGHTED(A1:A100, B1:B100), SUM(A1:A100)” to calculate both the weighted average and the total of the values in cells A1 to A100. This can be useful for getting a more detailed picture of the data.
• The COUNT function is often used with the AVERAGE.WEIGHTED function to count the number of cells in a range that contain numeric values. This can be useful for ensuring that the AVERAGE.WEIGHTED function is only calculating the weighted average of cells with numeric values, and ignoring any empty cells or cells with errors. For example, you could use the formula “=AVERAGE.WEIGHTED(A1:A100, B1:B100), COUNT(A1:A100)” to calculate the weighted average and the number of cells in the range that contain numeric values.
