Central Tendency: Demystifying "Average" Term

Skewness indicates whether the data is concentrated on one side. If the histogram is shifted to the left or the right side then the distribution is skewed otherwise, it's not skewed. There are two types of skewness namely right (positive) skew and left (negative) skew. In the right skew case, the 3 measurements will be: mode median mean. Right skew tells us that the outliers are located to the right.
