Skewness calculator
Measure the asymmetry of your data distribution. Positive skew = right tail, negative = left tail, zero = symmetric.

Interpreting skewness
Skew = 0: Symmetric (like normal distribution). Positive: Right-skewed (long right tail, mean > median). Negative: Left-skewed (long left tail, mean < median).
|Skew| < 0.5: approximately symmetric. 0.5–1: moderately skewed. > 1: highly skewed.
