Stem & Leaf And Dot Diagram
In this course, students will learn how to represent data clearly using Stem-and-Leaf diagrams and Dot diagrams. Students will understand how to organise raw data, display it in a structured form, and interpret the information to identify patterns, trends, and key values such as mean, median and mode.

Stem & Leaf
A stem-and-leaf diagram is a way of organizing and displaying data to make it easier to read and interpret. Each value is split into a stem (the leading digit or digits) and a leaf (the final digit), allowing the data to be arranged in order while keeping the original values visible.
- If the data set has two digits, the first digit is the stem, and the second digit is the leaf
- If the data set has three digits, the first two digits are the stem, and the last digit is the leaf
Dot Diagram
A dot diagram is a way of displaying data using dots above a number line. Each dot represents one value, and repeated values are shown by stacking dots vertically.
