As we know Box and Whisker Plot analyzes and explains the descriptive Statistics of the given data set.

The length of the box tells us about the variability of the data and the line across the box provides us with information about the centered data.

In the plot below, Group 2 has more variability than Group 1 because it has a longer box and whiskers. Group 1 ranges from approximately 3 to 7 while Group 2 ranges from roughly 1.5 to 9

The comparative length of both the whiskers(left and right side) taken with the position of the line inside the box can also give us a fair idea of the distribution of the sample data provided the sample data should be large enough to test.

Right ( Positive ) Skewed
