Calculate Mean Absolute Deviation in Excel

Understanding MAD in Excel

Mean Absolute Deviation (MAD) is a statistical measure used to quantify the spread of data points in a dataset. MAD is particularly useful as it is less influenced by outliers than standard deviation, making it a robust measure of dispersion.

Using the AVEDEV() Function

To calculate MAD in Excel, use the AVEDEV() function. This function computes the mean of the absolute deviations of data points from their mean, effectively ignoring the direction of each deviation.

Steps to Calculate MAD

Calculate MAD by selecting a cell and entering =AVEDEV(), followed by the range of data points within parentheses. For example, =AVEDEV(A1:A10) calculates the MAD for data in cells A1 through A10.

Benefits of MAD for Data Analysis

Employing MAD in data analysis provides more informed decision-making. Due to its resistance to outliers, MAD offers deeper insights and aids in making data-driven decisions.
