The stem and leaf plot key for three-digit numbers is represented as two digits in the stem and one digit in the leaf.If we plot data using stem and leaf and place it alongside the new data, we might be able to see a correlation between both the data and the frequency distribution of data.Given below are some important notes related to stem and leaf plots. Step 7: Plot the leaves in the column against the stem from lowest to the highest horizontally.Arrange it in ascending order starting from the lowest to the top. Step 6: List the stems in the stems column.Place the stem on the left column and the leaf on the right column. the lowest and the highest values among the data. Step 4: Determine the range of the data, i.e.Step 3: Identify the first digits as stems and the last digit as leaves.Step 2: Fix the stem and leaf plot key.Step 1: Look at the data and find the number of digits.Hence, the data values greater than 15 are 17, 25, and 29.įollow the steps for constructing a stem and leaf plot. From stem value 2, we get the data values 25 and 29. (d) List the data values greater than 15.įrom stem value 1, we get the data values 15 and 17. The numbers on the leaves against the value 0 on the stem are 2, 6, and 8. Combining the values of the stem and the leaves, we get the data values 25 and 29. The stem 2 means 20 and the leaf means 5 and 9. Then find the corresponding leaves on the right. Look at the stem column on the left and locate stem 2. (a) What are the leaf numbers for stem 2? Let us interpret the following data after studying the stem and leaf plot. If you combine the values of the stem and the leaves, you will get the data values. The stem is on the left and the leaf is on the right. The stem and leaf plot key helps us understand the data values. Thus, calculating the stem and leaf plot statistics is very easy. Mode is the data value that frequently appears. Mean of the data = Sum of data values ÷ Total number of values = (20 + 32 + 32 + 35 + 41) ÷ 5 = 160 ÷ 5 = 32. The data values are already in ascending order. Consider the following stem and leaf plot worksheet which shows 5 data values. Let's understand with help of an example. Stem and Leaf Plot Statisticsįinding the mean, median, and mode are a part of stem and leaf plot statistics. The decimal part will show on the leaf side. 4 on the stem and 2 on the leaf read as 4.2. For example, stem and leaf plot key 4 I 2 is 4.2.
The stem and leaf plot key (" | ") helps us understand how the data is organized on the stem and leaf plot with decimals. We can use stem and leaf plots with decimals the same way we use for whole numbers.
In the image given below, the stem values are listed one below the other in ascending order and the leaf values are listed left to right from the stem values in ascending order.Īs the stem and leaf plot definition states,Ħ I 7 ⇒ 6 on the stem and 7 on the leaf read as 67.Ħ I 8 ⇒ 6 on the stem and 8 on the leaf read as 68.ĩ I 0 ⇒ 9 on the stem and 0 on the leaf read as 90.ĩ I 1 ⇒ 9 on the stem and 1 on the leaf read as 91.ĩ I 8 ⇒ 9 on the stem and 8 on the leaf read as 98. For example, 46 is represented as 4 on the stem and 6 on the leaf and shown using stem and leaf plot key like this 4 I 6. This " | " symbol is used to show stem values and leaf values and it is called as stem and leaf plot key. Each data value is broken into a stem and a leaf.Ī stem and leaf plot is represented in form of a special table where each first digit or digit of data value is split into a stem and the last digit of data in a leaf. It is a graph that shows numerical data arranged in order. A stem and leaf plot also called a stem and leaf diagram is a way of organizing data into a form that makes it easy to observe the frequency of different types of values.
