Stem And Leaf Diagram In Statistics. The general purpose of a stem and leaf diagram is to provide a quick display of how the data are distributed across the range of their values. The process will be easiest to follow with sample data so lets pretend. We look at stem and leaf diagrams and how they can be used to illustrate discrete data. Some improvisation could be necessary to obtain a diagram that best meets that goal.
The tens column becomes the stem and the units become the leaf. The stem and leaf plot is used like a histogram. In this video you are shown how to represent raw data in different types of stem leaf diagrams. They evolved from Arthur Bowleys work in the early 1900s and are useful tools in exploratory data analysis. A Stemplot is used to draw quantitative data with fewer than 50 observations. In a stemplot left side entries are called stems.
To create the plot divide each observation of data into a stem and a leaf.
The tens column becomes the stem and the units become the leaf. The tens column becomes the stem and the units become the leaf. In a stemplot left side entries are called stems.

Generate an online stem and leaf plot or stemplot and calculate basic descriptive statistics for a sample data set with 4 or more values and up to 1000 values all non-negative. One simple graph the stem-and-leaf graph or stemplot comes from the field of exploratory data analysis.
