Stem and Leaf Charts
Understand the Problem
The question is asking for information about stem and leaf charts, which are used to display quantitative data in a way that retains the original values while providing a visual comparison of the distribution of the data.
Answer
A stem and leaf plot divides data values into 'stems' and 'leaves'.
A stem and leaf plot is a type of graph used to display quantitative data by dividing each data value into a 'stem' (first digit or digits) and a 'leaf' (last digit).

More Information
Stem and leaf plots are useful for showing the frequency of different values in a data set while retaining numerical data. They are similar to histograms but maintain the original data to some extent.
Tips
A common mistake is misplacing entries under the incorrect stem or not properly aligning leaves, which can distort data representation.
