In this example, the stem will be the tens place value column. The stem is made from all of the digits in the numbers except for the final digit. Create the stem by listing the first digits of the numbers. The minimum value is 1 and the maximum value is 41. Identify the minimum and maximum values in the data. Create a key by writing an example to explain the diagram.įor example, make a stem and leaf plot to represent the following data showing the ages of people who at a park.ġ5, 1, 28, 7, 5, 33, 41, 4, 10, 35, 24, 2, 32, 6, 11, 4, 12, 5, 37, 30. Represent the numbers from smallest to largest by writing the final digit of each number in the correct leaf.Draw a line between the stem and the leaves.Create the stem by listing the first digits of the numbers.Identify the minimum and maximum values in the data.Keys are particularly useful if the numbers being represented contain many digits, units or are made from decimal numbers. A key is made by writing out one example from the diagram, including units. When making a stem and leaf diagram, a key must always be included. Stem and leaf plots are used to display numerical data written as a list.Ī stem and leaf plot displays all data values and this allows the mode to be easily read. The numbers in a stem and leaf diagram must be listed in order.Ī stem and leaf plot is read by combining the digits in the stem with the digit in the leaf. A stem and leaf plot is used to organise data visually so that the distribution, skew, outliers and mode can easily be seen. Each number is written with its first digits in the ‘stem’ and its final digit listed in the ‘leaf’. A stem and leaf plot is a table in which numbers are represented by one digit, listed in order.
