The median is the middle value in a set of ordered data.

How to Find the Median on a Stem and Leaf Plot The maximum is $55 and the minimum is $12. Here is another example of finding the range on a stem and leaf diagram. For example if the maximum value is 41 and the minimum value is 1, the range is 41 – 1 which equals 40. On a stem and leaf plot, the minimum is the first value and the maximum is the last value. The range is the maximum value subtract the minimum value. How to Find the Range on a Stem and Leaf Plot Combine the digits in the stem with each digit in the leaf to read each number. On a stem and leaf plot the stem is to the left of the vertical line and the leaf is to the right. To make a key on a stem and leaf plot, write any number from the diagram and explain how it is read. Create a key by writing an example to explain the diagram. Now we list the numbers with a 4 in the tens column. Now we list the numbers with a 3 in the tens column.ģ0, 32, 33, 35 and 37 are represented as 3| 0 2 3 5 7. Now we list the numbers with a 2 in the tens column. The numbers are listed by their final digit only. We only use the 1 in the tens column once in the stem of the diagram. We list the final digits of these numbers in line with the 1 in the stem.ġ0, 11, 12 and 15 are listed as 1| 0 1 2 5. Now we list the numbers with a 1 in the tens column.
If any numbers are repeated, they are still listed multiple times. They are listed in order in line with the 0 in the stem. Now we list the other numbers with zero tens. We place it in the leaf alongside the 0 in the stem. We start with the numbers with zero tens. 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. Therefore the stem is a list of numbers from 0 to 4. In the maximum value of 41, there are 4 tens. In the minimum value of 1, there are 0 tens. 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.
