How to create a box-and-whisker plot: To draw a box-and-whisker plot you need five pieces of information, called the five-number summary: the smallest value, the lower quartile (LQ), the median, the upper quartile (U0) and the largest value. An outlier is a value that is much smaller or much larger than the other values. An outlier is a point less than the LQ-1.5x 1QR or greater than the UQ+1.5xIQR.
Suppose a researcher collects data on the air pollution levels, measured in milligrams per cubic meter, for both urban and rural areas in 35 states. The data is plotted with urban air pollution levels on the horizontal axis and rural air pollution levels on the vertical axis. Nevada is an outlier in the ?x‑direction. What must be true about this state? The urban air pollution levels for this state are much higher or lower than the rest of the states in the data set. The rural air pollution levels for this state are much higher or much lower than the rest of the states in the data set. This state is an influential observation. The rural air pollution levels for this state are much higher or lower than other states in the data set that have similar urban air pollution levels. The absolute value of the residual of this state is large.
