Calculating Mean Absolute Deviation with Desmos

This video tutorial explains the concept of mean absolute deviation (MAD), which measures the average distance of data points from the mean. The instructor provides examples to demonstrate how to calculate MAD using Desmos, and also covers related statistical concepts like the five number summary, range, interquartile range, and outliers. The video emphasizes practical application by walking through examples and using Desmos for calculations.

What does MAD stand for in statistics?

• Maximum Allocated Division

• Mean Absolute Deviation

• Mode Absolute Difference

• Median Aligned Data

How is the mean absolute deviation calculated?

• Difference between the highest and lowest values

• Average of absolute deviations from the mean

• Average of squared deviations from the mean

• Sum of deviations from the median
