Explain Skewness With Example. Jan 25 2021 Skewness refers to a distortion or asymmetry that deviates from the symmetrical bell curve or normal distribution in a set of data. For example if a neighborhood has 100 houses with 99 of them having a price of 100000 while only one sells at 1000000 then the frequency of houses selling at 100000 will be maximum towards the left side of the distribution since it is a lower value than 1000000.
The variation in housing prices is a positively skewed distribution. In a skewed distribution the curve is extended to either left or right side. Example Definition of Skewness.
A distribution or data set is symmetric if it looks the same to the left and right of the center point.
