Calculate Range, Standard Deviation, Variance, Coefficient of Variation, and Mean Absolute Deviation for Grouped Data
How to use:
- Enter class intervals in the first text area (comma separated, e.g., 0-10, 10-20)
- Enter corresponding frequencies in the second text area (comma separated, e.g., 5, 10)
- Click the Calculate button to see the results
- The table will show x (midpoint), f, f·x, f·x², f·|x-mean|, and f·(x-mean)² values
- Range, Standard Deviation, Variance, Coefficient of Variation, and Mean Absolute Deviation will be calculated
- All calculation steps will be shown for better understanding
