Stem leaf plot calculator8/31/2023 ![]() Key: 6-9 means 69 The key is based on entirely what numbers you have used in the stem and leaf plot. To find this value, we can write out each of the individual values in the dataset and find the middle value:ĭataset: 4.5, 4.7, 4.9, 5.2, 5.4, 6.1, 7.8, 8.2, 8.2, 8.2, 8. Here is the marks that each student has got after an exam in the class ploted out in a stem and leaf plot. The median is defined as the “middle” value of the dataset. Use the Stem and Leaf plot to answer the following questions. VAR Once this item has been selected, complete the syntax: Stemleaf(mct,0) Then press enter to see the Stem and Leaf plot and esc to exit. Question 4: What is the median of the dataset? To generate a Stem and Leaf plot either type the command (Program name) or select StemLeaf from the Variable menu. The mode is the value that occurs most often. For example, if a data point is 42, the stem is 4 and the leaf is 2. The stem value contains all the digits of a data point except the final number, which is the leaf. The stem values divide the data points into groups. Question 3: What is the mode of the dataset? To make a stem and leaf plot, split each data point into a stem and leaf value. ![]() The range of the dataset is the difference between the largest and smallest value. Question 2: What is the range of the dataset? Question 1: What is the max value in the dataset? Suppose we have the following stem and leaf plot with decimals: Example 3: Interpreting a Stem and Leaf Plot with Decimals ![]() Once again, the key at the bottom of the plot tells us how to interpret the values in the plot. If we define the integer and the first value after the decimal place as the stem, and the second value after the decimal as the leaf, then we can create the following stem and leaf plot: When creating this stem and leaf plot, it’s important to include a key at the bottom so the reader knows how to interpret the values in both the stem and the leaf. If we define the digits in front of the decimal as the stem, and the digits after the decimal as the leaf, then we can create the following stem and leaf plot: The following examples illustrate how to create stem and leaf plots with decimals. While stem and leaf plots are typically used with integer values, they can also be used for values with decimals as well. If we define the first digit in each value as the “stem” and the second digit as the “leaf” then we can create the following stem and leaf plot: A stem and leaf plot is a type of plot that displays data by splitting up each value in a dataset into a “stem” and a “leaf.”įor example, suppose we have the following dataset:ĭataset: 12, 14, 18, 22, 22, 23, 25, 25, 28, 45, 47, 48 ![]()
