Finding the mean absolute deviation (MAD) in Excel requires knowledge of specific formulas and steps. MAD is a measure used to understand variability in a set of data.
Excel users can calculate MAD by using functions like AVERAGE and ABS, which can become cumbersome with large datasets.
This guide will show you how to calculate MAD in Excel, but you'll discover how Sourcetable's AI chatbot can instantly analyze your data and calculate MAD just by asking - try it now at Sourcetable.
To calculate Mean Absolute Deviation (MAD) in Excel, use the AVEDEV()
function. MAD measures data dispersion and is less affected by outliers compared to standard deviation.
The AVEDEV()
function computes MAD by taking the mean of absolute deviations from the mean. Input either individual numbers, up to 255, or a range of values.
To calculate MAD, input your dataset into Excel and then apply the AVEDEV()
function to this dataset. This function considers absolute differences, providing a robust measure of variability.
Utilizing the MAD metric in Excel offers a more reliable dispersion measure, less skewed by outliers. This can support more accurate data analysis and decision-making processes.

First, calculate the mean using =AVERAGE(A1:A5). Then, calculate absolute deviations for each data point using =ABS(A1-$B$1). Finally, calculate MAD by using =AVERAGE(B1:B5) on the absolute deviations.
Yes, use the formula =MEDIAN(IF(ISBLANK(A24:N24),'',ABS(A24:N24-MEDIAN(A24:N24)))) and enter it using Ctrl-Shift-Enter as it's an array formula.
You need three Excel functions to calculate MAD: the AVERAGE function for calculating the mean, the ABS function for calculating absolute deviations, and AVERAGE again for the final MAD calculation.
