Understanding Skewness
Skewness is a measure of the asymmetry of a probability distribution. It tells us about the direction and extent of the distribution's lean.
- Positive Skew (Right-skewed): The tail is longer on the right side. Most of the distribution is concentrated on the left. Mean > Median > Mode.
- Negative Skew (Left-skewed): The tail is longer on the left side. Most of the distribution is concentrated on the right. Mean < Median < Mode.
- Zero Skew: The distribution is symmetric. Mean ≈ Median ≈ Mode.
This calculator helps you quickly determine the skewness of a discrete random variable, providing insights into the shape of your data's distribution. Use it to analyze datasets in various fields, from finance to environmental science.
