Stem and leaf plots have data placed into order from lowest to highest. The stem-and-leaf plot is a graph that is similar to a histogram but it displays more information. Scroll down the page for more examples and solutions on how to construct and use stem-and-leaf plots. They would create the stem and leaf plot shown in G2:H6. A stem and leaf diagram is one way of grouping data into classes and showing the shape of the data. The median is always a number in the data set. One simple graph, the stem-and-leaf graph or stemplot, comes from the field of exploratory data analysis. Why to use Stem Plots? A stem-and-leaf plot, on the other hand, summarizes the data and preserves the data at the same time. A stem and leaf plot uses the digits of data values to organize a data set. 3. The 'stem' is on the left displays the first digit or digits. We can divide the number 56 into a stem and a leaf.

We could divide 85 into a stem of 8 and a leaf of 5. You can use a steam-and-leaf plot to find and display the median, the LQ and the UQ. The median is at (22 + 22)/2 = 22 and is marked by a box. Thus it is a three step process: 1) choose the stems based on scanning the data, 2) add the leaves in the order encountered, 3) reorder the leaves on each stem from smallest to largest. A stem and leaf diagram shows numbers in a table format. The stem and leaf plot shows how data are distributed. d) There are 18 data values and already ordered in the stem and leaf diagram. 5 is the stem and 6 is the leaf. Part 1: Reading a Stem and Leaf Plot The Stem and Leaf Plot is an interesting way to showcase data. Student correctly created and ordered data for 1 of the stem plots with correct labels, title, and intervals: the other shows some mistakes. The digit in the stem represents the tens and the digit in the leaf represents the ones. The observations range in value from 10 to 39, so the stem and leaf plot should have stems of … The first row becomes: Problem A3 Use the following Activity to create an ordered stem and leaf plot on paper.

A stem-and-leaf plot is an organization of numerical data into categories based on place value. It provides a table as well as a picture of the data and from it we can readily write down the data in order of magnitude, which is useful for many statistical procedures. So you could view this as 0, 0, 4, or 4 turtles. Assignment is done to the stem list by correctly pairing the unit digit (leaf) with the stem. There is always a mode for each set of data.
