pdf Mean Absolute Deviation

This worksheet provides clear, step-by-step instruction and practice for calculating mean absolute deviation (MAD). A fully worked example guides students through the complete three-step process: finding the mean of a data set, determining the absolute distance of each value from the mean, and then calculating the mean of those distances. The example models precision, organization, and proper rounding to the nearest tenth.

After reviewing the modeled example, students apply the same structured process to twelve varied data sets. The problems include small and large numbers, as well as data sets with different numbers of elements, reinforcing procedural consistency. Because students must keep all distances positive and compute multiple averages, the worksheet strengthens conceptual understanding of variability as well as computational fluency.

This resource works well as guided instruction when introducing mean absolute deviation, independent practice, homework, review, or formative assessment within a statistics and data analysis unit.
