Box and Whisker Plots

A Box and Whisker Plot is a graphical representation of a dataset that displays its minimum, lower quartile (Q1), median, upper quartile (Q3), and maximum values.

The lower quartile (Q1) represents the value below which 25% of the data falls.

The upper quartile (Q3) represents the value below which 75% of the data falls.

The median is the middle value of the dataset when it is ordered from least to greatest.

The 'whiskers' indicate the range of the data, specifically the minimum and maximum values.

The minimum value is the smallest number in the dataset.

The maximum value is the largest number in the dataset.

The purpose of a Box and Whisker Plot is to summarize and visualize the distribution of a dataset.

Outliers can be identified as points that fall outside the range defined by the whiskers.

The interquartile range (IQR) is the difference between the upper quartile (Q3) and the lower quartile (Q1), representing the middle 50% of the data.
