Question
In a dataset, if the mean is significantly greater than
the median, the distribution is most likely:Solution
- Skewness refers to the asymmetry of a distribution.
- In a symmetrical  (like normal) distribution, the mean, median, and mode are equal.
- In a positively skewed  (right-skewed) distribution, the tail on the right side is longer. A few extremely high values pull the mean  toward the right tail, making it greater than the median , which is more resistant to outliers.
- In a negatively skewed  (left-skewed) distribution, the mean is less than the median.
Therefore, "mean > median" is a hallmark of positive skewness.
