For data values in the hundreds or thousands, the largest digit is put in the stem with the remaining digits are put in the leaves. A stem-and-leaf plot is similar to a histogram but contains the exact value of every data point. Stem-and-leaf plots are therefore useful for determining common statistical metrics such as the mode and median.
