Calculation Example

Let's do a sample calculation:

Example:
Data Set:
[2, 4, 4, 4, 5, 5, 7, 9]
Calculation Type:
Sample MAD
Data Type:
Individual Values
Result:
Mean: 5.0
MAD: 1.5
Count: 8
Range: 7
Step-by-Step Calculation:
  1. Calculate Mean: (2+4+4+4+5+5+7+9) ÷ 8 = 40 ÷ 8 = 5.0
  2. Calculate Absolute Deviations: |2-5|, |4-5|, |4-5|, |4-5|, |5-5|, |5-5|, |7-5|, |9-5|
  3. Absolute Deviations: 3, 1, 1, 1, 0, 0, 2, 4
  4. Sum of Absolute Deviations: 3 + 1 + 1 + 1 + 0 + 0 + 2 + 4 = 12
  5. Calculate MAD: 12 ÷ 8 = 1.5
