Option 2 : Mode > Median > Mean

**Explanation**

**If skewness is negative**, the mean is smaller than the median and the distribution has a large tail of small values.

The relation in mean, median and mode in positive skewed

**Mean < Median < Mode**

__Key Points__

Skewness: measure the asymmetry of a distribution about its peak;

It is a number that describes the shape of the distribution.

It is often approximated by Skew = (Mean - Median) / (Std dev).

If skewness is positive, the mean is bigger than the median and the distribution

The relation in mean, median and mode in positive skewed

Mean > Median > Mode

has a large tail of high values.
