What is difference between skewness and kurtosis.
Answer
Skewness measures asymmetry; kurtosis measures the 'tailedness' of the distribution.
Skewness measures the asymmetry of a probability distribution around its mean. A positive skew indicates a heavier tail on the right side, while a negative skew indicates a heavier tail on the left side.
Kurtosis measures the "tailedness" (or peakedness) of a probability distribution. It mathematically describes how often extreme values (outliers) occur compared to a perfectly normal distribution (categorized as Mesokurtic, Leptokurtic, or Platykurtic).
