It is all in how you do the graph and what numerical information you are trying to convey. However, in the split stem and leaf plot, we can conclude that the main cluster of data is between 155 to 164 cm which is a more accurate conclusion. Similarly, a stem and leaf plot is similar to a histogram but is usually provide more information for a relatively small data set. Stem and leaf offer a quick and novel way for simultaneously sorting and displaying data sets where each number in the data set is divided into two parts: stem (all numbers except the last digit) and a leaf (only the last digit). Accessed 4 March, 2023. 4. picture the distribution of values. Similarly, a stem and leaf plot is similar to a histogram but is usually provide more information for a relatively small data set.
