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.
