A box plot is frequently used in statistics to convey graphical statistics by displaying the maximum values, minimum value, the first quartile, the third quartile, and the median. The lowest point is the minimum values while the highest point is the maximum value. The top of the box represents the third quartile and the bottom represents the first quartile. The bar in the middle of the box is the median of the data set. Through box plots, statistical data is easily be evaluated. For example, the photo above displays the vanity height of buildings in China, USA, UAE, and others. The maximum in the United States is about 37% while the minimum is about 2%. The third quartile is close to 21%, the first quartile around 3%, and a median of 6%. These percentages can be compared to other, while outliers must be taken into consideration.
