Mean Deviation About Mean Formula

Gradient Text Example

Chesser Ai Answer

Mean deviation about the mean is the average of absolute deviations from the mean.

Key Concepts

  • Concept: Definition of MAD about mean
  • Concept: Absolute deviations used
  • Concept: Measures data dispersion

Steps

  1. Action: Compute the mean
  2. Action: Compute |x_i – mean| for each value
  3. Action: Average the deviations: sum/n

Formula

$$text{MAD}_{text{mean}} = frac{1}{n} sum_{i=1}^{n} left| x_i – bar{x} right|$$
