For example, 23 has stem two and leaf three. The leaf consists of a final significant digit. To create the plot, divide each observation of data into a stem and a leaf. It is a good choice when the data sets are small. The actual weights of random samples of 50 female and 50 male university students enrolled in an introductory Statistics course at the University of Auckland are displayed on the back-to-back stem-and-leaf plot below. One simple graph, the stem-and-leaf graph or stemplot, comes from the field of exploratory data analysis. The actual weights of a random sample of 50 male university students enrolled in an introductory Statistics course at the University of Auckland are displayed on the stem-and-leaf plot below.Īctual weights of male university students (kg)Įxample 2 (Back-to-back stem-and-leaf plot) Stem-and-leaf plots are particularly useful when the number of values to be plotted is not large. To compare the distribution of a numerical variable for two categories of a category variable, a back-to-back stem-and-leaf plot can be drawn, in which the stem is placed at the centre and the leaves for the values of the numerical variable for one category are drawn on one side of the stem and the leaves for the other category are drawn on the other side. Ideally the numbers in the ‘stem’ represent the highest place-value digit in the values and the ‘leaves’ display the second highest place-value digits in each individual value. Students should already be familiar with. Editable Seating Plan Back to School Leaf Theme Lesson Planning Kit Back. construct a back-to-back stem-and-leaf plot from given data sets, with stems of varying numbers of digits, analyze and interpret data given as a back-to-back stem-and-leaf plot. A graph for displaying the distribution of a numerical variable that is similar to a histogram but retains some information about individual values. 90 Top Back-to-back Stem And Leaf Plots Teaching Resources curated for you.
