# Box and Whisker Plot

The box-and-whisker plot (also known as box plot) is an exploratory graphic, created by John W. Tukey, used to show the distribution of a data set. Statistics assumes that data points are clustered around some central value. The "box" in the box-and-whisker plot contains, and thereby highlights, the middle half of these data points.It is more like a histogram and is usually drawn alongside a number line.

Box plot is used to represent differences among populations as we don't assume the distribution to which it belongs which helps us to identify the degree of dispersion (spread) and skewness in the data and also outliers for the given data.They can be drawn vertically as well as horizontally.

The advantage of using boxplot is it takes less space and it is helpful to compare the data.
