There are many different activities in which you can involve a stem and leaf plot.

Stem and leaf plots are very flexible this way.Įxample: The average heights of ten high school students in inches are reported below. It is all in how you do the graph and what numerical information you are trying to convey.

For instance, your stems may be the ones place while your leaves are the decimal points. It is not that different from a normal stem and leaf plot, only in which you have to designate your stems and leaves to where you want them to begin. When you are tracking your leaves, all you have to do is include the decimal points as well. There are some stem and leaf plots out there that have decimals along with it. Then identify the stem and respective leaves for male and female. Sort the data in ascending order for both male and female. In other words, it helps to compare different sets of data together at the same time.Įxample: For the above example, add 23 female students’ books reading data. Q3 (Upper Quartile) = Find ¾(n+1)= 3*24/4= 18 th value is 44 books.īack to back stem and leaf diagrams can be used to compare different sets of data relating to the same subject.Q1 (Lower Quartile) = Find ¼ (n+1) =24/4=6 th value is 18 books.Mode: The number which appears most often in a set of numbers= 32 number repeated twice.Median: The median is the middle value = n+1/2 = 23 +1/2 =12 th value =29 books.Also, note that leaves are in numerical order. Then for each stem, record all the leaves associated with that stem. Finally, you can compute the median, mode, and Quartiles.Įxample: A teacher asked 23 of her male students how many books they had read in the last 4 years.The stem and leaf plot always has a Key, which normally describes what the entry means (stem and a leaf).Then for each stem, record all the leaves associated with that stem.Draw a line and lists the possible stems in a single column from lowest to highest on the left side of the line.Analyze the data to determine the stem and the leaf.Sort the numerical data in ascending order.There are many different ways to create a stem and leaf plot but they all serve the same purpose at the end of the day. Easy to compare different sets of data together at the same time.Organizes data so it is easy to compute the median, mode, and quartiles.Shows data in an organized way, so it can be analyzed easily.A stem and leaf plot looks something like a bar graph. It will organize data visually and will be able to interpret data and draw conclusions using the plot. Stem and leaf plots are methods for showing the frequency with which certain classes of values occur. The difference with this type of graph is that it preserves the actual data as well as being the most like a frequency distribution. Stem and leaf plots have been around for decades and are like a cross between a histogram and a check sheet. Stem and leaf plots are some of the best ways to not only study but track information as well. Significance of Stem and Leaf PlotĪ stem and leaf plot was developed by John Tukey an American mathematician in 1977. For example, in the numbers 38 and 52, the stems are 3 and 5, while the leaves are 8 and 2. Stem and leaf offer a quick and novel way for simultaneously sorting and displaying data sets where each number in the data set is divided into two parts: a stem (all numbers except the last digit) and a leaf (only the last digit). It is used to organize data as they are collected. A stem and leaf plot, also known as a stem plot, is a technique to categorize either continuous or discrete values.
