Mean Absolute Deviation (MAD)
by Anonymous
Move five values to measure each distance from the mean and watch the mean absolute deviation grow as the data spreads out.
About this app
Mean Absolute Deviation (MAD) is an interactive math learning app that shows how to calculate the average distance of data values from their mean. Adjust five values, observe their deviations and MAD, explore how increasing spread changes MAD while the mean stays fixed at 10, and practice with multiple-choice challenges.
Use cases
- Middle school students learning measures of spread
- Teachers demonstrating MAD with visual examples
- Learners practicing mean and absolute deviation calculations
- Anyone exploring how data spread affects MAD
Features
- Adjust five data values with plus and minus controls
- Displays the mean, absolute deviation sum, and MAD calculation
- Explores spread while keeping the mean fixed at 10
- Includes four MAD calculation missions
- Provides four multiple-choice quiz questions with answer feedback and streak tracking
