Formula:
Dispersion refers to the spread or variability of a dataset. This calculator provides several key measures:
- Mean (μ or x̄): The average of all numbers.
Formula: Σx / N (sum of all values divided by count) - Range: The difference between the highest and lowest values in a dataset.
Formula: Max Value - Min Value - Variance (Population σ2; Sample s2): Measures how far each number in the set is from the mean.
- Standard Deviation (Population σ; Sample s): The square root of the variance, indicating the typical distance of data points from the mean.
