What is Skewness Calculator?

▾

Skewness measures the asymmetry of a probability distribution. Positive skew (right tail) means a few large values pull the mean up; negative skew (left tail) means a few small values pull it down.

Calkulon makes complex calculations simple — built for students and everyday problem-solvers.

How to Skewness Calculator

▾
  1. 1Sample skewness = (n/((n−1)(n−2))) × Σ((xᵢ−x̄)/s)³
  2. 2Symmetric: skewness ≈ 0
  3. 3Right-skewed: mean > median > mode
  4. 4Left-skewed: mean < median < mode

Worked Examples

▾
Example 1
Given:Income data with a few very high earners
תוצאה:Positively skewed (right tail); mean > median
Example 2
Given:Test scores where most are near the top
תוצאה:Negatively skewed (left tail)

Frequently Asked Questions

▾
Q

What does skewness tell us?

A

Positive skewness: tail on right (long right tail). Negative: tail on left. Zero: symmetric.

Q

When is data considered skewed?

A

Typically, |skewness| > 0.5 indicates noticeable skew. > 1 is highly skewed.

Q

How is skewness different from kurtosis?

A

Skewness measures asymmetry. Kurtosis measures tail weight (how extreme the values are).
