What is a Stem & Leaf Plot?

2. Organizing Data

   The Stem values are listed vertically.

   The leaf values extend horizontally from the stems.

   The arrangement groups the scores and each leaf shows individual values with each group.

1. Splitting Data

   Each data value is divided into two parts:

   The stem: Consist of the first digit or digits

   The leaf: Usually represents the last digit.

A stem-and-leaf plot is a graphical representation of data that helps visualize the distribution of values. Here’s how it works:

Advantages

Simplicity and Clarity

Stem-and-leaf plots are straightforward to construct and interpret. They organize data in a way that makes the shape of the distribution easy to see at a glance.

Data Retention

Unlike other summary statistics or visualizations like histograms, stem-and-leaf plots retain the original data values. This feature allows for more detailed analysis and verification.

Multiple Choice

Stem and leaf plots use plants to represent digits.

• True

• False

Multiple Choice

Stem and leaf plots dismantles the original data rather than retain it.

• Sometimes

• True

• False

Multiple Choice

Stem and leaf plots are easy to interpret and construct.

• False

• True

Disadvantages

• Limited scalability: Stem and leaf plots are best suited for small to medium-sized datasets. They can become cluttered and difficult to interpret with large datasets.

• Not ideal for continuous data:

  Stem and leaf plots are better suited for discrete or categorical data. They can be less effective for continuous data, as the stem and leaf structure can be less intuitive.

• Difficult to compare multiple datasets: Comparing multiple stem and leaf plots can be challenging, especially if the datasets have differentf scales or ranges.

• Not easily customizable: Stem and leaf plots have a fixed structure, making it difficult to customize them to suit specific needs or visual preferences.

Multiple Choice

Bar graphs are more visually appealing than stem and leaf plots.

• True

• False

Multiple Choice

Stem and leaf plots are best suited for large data sets.

• True

• False

Draw

Represent the following data as a stem and leaf plot:

22, 32, 45, 67, 98.

Multiple Choice

Stems are the last digits.

• True

• False

Complete the following in two teams:

Find the mean, mode, median and range from the table.
You have 6 minutes, the group that finishes firsts with the correct answers wins.

​Stem	​Leaf
​1	​2 5 7
2​	​0 3 9
3​	​ 6 77
4​	​0 8 9

ANSWERS

MEAN: 30.25
MODE: 37
MEDIAN: 32.5
RANGE: 37
