Stem and Leaf Plot Key Examples
- Key: 3 | 2 = 32% – Denotes number and percentage
- Key: 3 | 2 represents 3.2 seconds – Denotes decimal location and units
- Key: 3 | 2 represents 32 meters – Shows number and units
- 3 | 2 is 32 – This is the bare minimum, but is very common. (Note it is not even labeled “Key”)
How do you create a stem and leaf plot?
Steps for Making Stem-and-Leaf Plots
- First, determine the smallest and largest number in the data.
- Identify the stems.
- Draw a with two columns and name them as “Stem” and “Leaf”.
- Fill in the leaf data.
- Remember, a Stem and Leaf plot can have multiple sets of leaves.
What are the properties of a stem and leaf plot?
Stem and leaf plots display the shape and spread of a continuous data distribution. These graphs are similar to histograms, but instead of using bars, they show digits. It’s a particularly valuable tool during exploratory data analysis. They can help you identify the central tendency, variability, skewness of your distribution, and outliers.
How to interpret stem and leaf plots?
- A stem and leaf plot is a table in which numbers are arranged into a ‘stem’ and a ‘leaf’.
- Write the last digit of each number in the leaf.
- All digits in front of the last digit are written in the ‘stem’.
- The numbers must be written from smallest to largest.
- Numbers with the same front digits share a ‘stem’.
How to describe data on a stem and leaf plot?
Data can be shown in a variety of ways including graphs, charts, and tables. A stem-and-leaf plot is a type of graph that is similar to a histogram but shows more information by summarizing the shape of a set of data (the distribution) and providing extra detail regarding individual values.

What is a double stem and leaf plot?
This type of Double Stem and Leaf plot contains three columns, each separated by a vertical line.
What is a stem and leaf?
Ans: A stem and leaf is a table used to display data. The 'stem' on the left side displays the first digit or digits. The 'leaf' is on the right side and displays the last digit.
What is a stem and leaf plot?
A stem and leaf plot is a plot where each data value is split into a leaf (the last digit) and a stem (the other digits). For example, 12 on the stem and 7 on the leaf read like 127, and 127 is written according to stem and leaf plot key 12 I 7.
How to plot 3 digit numbers on a stem and leaf?
To plot a 3 digit number on a stem and leaf plot we will write the starting two digits under the stem and the last digit of each value will come under the leaf. For example, 149 is the value so we will plot 14 under stem and 9 under the leaf.
Why is a stem and leaf plot best?
Because a stem-and-leaf plot represents each data value, it is best when the sample size is less than approximately 50. If the sample is greater than 50, the data points on the plot may extend too far, and the distribution may be difficult to assess.
What does the leaf unit on the top of the plot mean?
The "leaf unit" at the top of the plot indicates which decimal place the leaf values represent .
What is an outlier in a stem and leaf plot?
Outliers. Outliers, which are data values that are far away from other data values, can strongly affect your results. On a stem-and-leaf plot, isolated values at the ends identify possible outliers. For example, the last value at the bottom of this plot could be an outlier.
What does skewness mean in a graph?
When data are skewed, the majority of the data are located on the high or low side of the graph. Skewness indicates that the data may not be normally distributed. Often, skewness is easiest to detect with a histogram or a boxplot.
What is a Stem and Leaf Plot?
The Stem and Leaf plot is a concept in mathematics that makes it more fun. In addition to this, aside from making it more fun, it helps in dealing with loads of data efficiently and effectively. The “ stem ” is basically on the left side that displays the first digit. However, the “ leaf ” is on the right side.
History of Stem and Leaf Plot
This diagram is from Arthur Bowley ’s work in 1990 and is considered one of the smart tools in exploratory data analysis. The tool got popular and was widely being used by mathematicians and researchers.
Shapes of Stem and Leaf Plots
The Stem and Leaf plot is primarily a table that is separated by a vertical line. Thus, the left column has all the stems, and the right column has all the leaves that contain numbers associated with the numbers in the left column.
Usage of Stem and Leaf Plots
As mentioned above, Stem and Leaf plots are widely being used in mathematics and research. This is because it splits the data in a smart way and enhances its ability. In addition to this, it has extensive use in exploratory research as well. Other than this, the Stem and Leaf plots are also being used in:
How to Make Stem and Leaf Plots?
The Stem and Leaf plot is not complex anymore. In fact, it is fun. It has made mathematics fun for us. Thus, if you plan to create your own diagram, you can follow the below-mentioned steps one by one.
How to Create Stem and Leaf Plots in Excel?
Creating a Stem and Leaf diagram in Excel is as easy as creating it on paper. We have mentioned the steps for you. Following the below-mentioned method, you will be able to create a Plot and Leaf diagram in Excel. Let’s begin.
Stem and Leaf Plots Examples
For Stem and Leaf plots with hundreds, there are three digits. So, the method is to mention the first two digits in the first column of the stem. And the rest of the digits are mentioned in the second column of “Leaf”.
What is stem and leaf plot?
Let's Review: A stem and leaf plot is a great way to organize data by the frequency. It is a great visual that also includes the data. So if needed, you can just take a look to get an idea of the spread of the data or you can use the values to calculate the mean, median or mode.
Can a stem and leaf plot be turned into a histogram?
A stem and leaf plot can quickly be turned into a histogram as well to show the data using bars. Recall that a histogram shows the data in intervals. The intervals would be of size ten. Here is a set of data on showing the test scores on the last science quiz.
What is a stem and leaf plot?
A Stem and Leaf Plot is a special table where each data value is split into a "stem" (the first digit or digits) and a "leaf" (usually the last digit). Like in this example:
Where is the stem in a score?
The "stem" values are listed down, and the "leaf" values go right (or left) from the stem values. The "stem" is used to group the scores and each "leaf" shows the individual scores within each group.
