The AVEDEV function in Google Sheets is a powerful statistical tool used to measure the variance within a dataset. It calculates the average of the absolute differences between each data point and the mean of the dataset, providing insights into the data’s dispersion. This function is particularly useful for understanding how spread out the values are within a given set of data, aiding in data analysis and visualization.

Syntax

AVEDEV(value1, [value2, ...])

• value1: The first dataset or value to consider.
• value2: Additional datasets or values (optional).

Example #1

AVEDEV(A1:A5)

This function computes the average of the absolute deviations for the values in cells A1 through A5. For example, if the values are 5, 7, 3, and 8, the result would be approximately 1.5.

Example #2

AVEDEV(10, 23, 32, 15)

Here, the function calculates the average of the absolute deviations of the numbers 10, 23, 32, and 15 from their mean, yielding a result of about 8.25.

Example #3

AVEDEV(B2:B10)

This function evaluates the average absolute deviations of values in the range B2 to B10. If the values are 1, 2, 3, 4, 5, 6, 7, 8, the AVEDEV would be approximately 2.67.

Error handling

• DIV/0!: This error occurs if there are no values in the specified range, leading to a division by zero.
• VALUE!: This error indicates that the input data contains non-numeric values, which cannot be processed by the function.
• N/A: This error shows when one or more references are invalid or missing.

Conclusion

In summary, the AVEDEV function in Google Sheets is an essential resource for analyzing data dispersion. By determining the average of the absolute deviations from the mean, it offers valuable insights into the variability within a dataset. This makes it a crucial tool for professionals engaged in data-driven decision-making and analysis.
