Lets consider a set of data values. 55, 98, 62, 87, 90, 44, 58, 49, 54, 154 Sort the data in ascending order 44, 49, 54, 55, 58, 62, 87, 90, 98, 154 Stem | Leaf 4 | 4, 9 5 | 4, 5, 8 6 | 2 8 | 7 9 | 0, 8 15 | 4 Here leaf represents the once place and the rest of the numbers are represented in stems side. When there is repeated number of data like 54, 55, 58, it would look like 5 | 4, 5, 8.
