## How to Estimate Skewness ### Pearson's Second Coefficient of Skewness **Skewness = 3 * (Mean - Median) / Standard Deviation** - Positive skewness: The right tail is longer; the mean exceeds the median. - Negative skewness: The left tail is longer; the mean is below the median. - Zero skewness: The distribution is symmetric. This is an approximation. The exact moment-based skewness requires raw data.

हल किया गया उदाहरण

A dataset has mean 55, median 50, and SD 10. Estimate the skewness.

  1. 01Skewness = 3 * (55 - 50) / 10
  2. 02= 3 * 5 / 10
  3. 03= 15 / 10 = 1.5
  4. 04Positive value indicates right skew
