About Descriptive Statistics

Central Tendency measures where most values in a distribution fall.

Dispersion measures how spread out the values are.

Shape describes the pattern of the distribution.

Formulas Used:

Mean: Sum of values / count
Variance: Σ(xᵢ - x̄)² / (n-1)
Skewness: Measures asymmetry
Kurtosis: Measures tailedness

Note: For frequency data, ensure proper formatting (value:frequency).
