16.9 Stem and leaf plots
Stem-and-Leaf Plots
Learn how a stem and leaf plot organizes numerical data by place value, how to read one, and how to build your own step by step.
What You'll Learn
Identify the stem as the leading digit or digits and the leaf as the trailing digit of each data value
Order data from least to greatest before splitting each value into a stem and a leaf
Read a stem and leaf key correctly to recover the original data values
Build a stem and leaf plot by listing stems once and attaching every matching leaf in order
Compare two related data sets side by side using a back-to-back stem and leaf plot
Recognize when a stem and leaf plot is a better choice than a histogram or bar graph for small data sets
What You'll Practice
1
Creating stem and leaf plots from lists of numbers
2
Ordering leaves from least to greatest within each stem
3
Finding measures of central tendency using completed plots
4
Converting between stem and leaf plots and ordered data lists
Why This Matters
Stem and leaf plots help you organize and analyze data quickly while keeping all original values visible. This skill is essential for statistics, data analysis in science classes, and understanding how to compare datasets efficiently.
