1. Stem and Leaf Plot By: Dylan Henry, Brett Marberger, and Patty O’Neill

2. Definition • Stem-and-leaf plots are used to show the rate at which certain values occur. This would be used if you are a teacher and you need to record test scores. http://www.purplemath.com/modules/stemleaf.htm

3. http://chaversmapcatelog.blogspot.com/2010/12/stem-and-leaf-plot.htmlhttp://chaversmapcatelog.blogspot.com/2010/12/stem-and-leaf-plot.html These are test scores from a Science test.

4. Necessary Data • To have a stem and leaf plot, you need a single set of data that is organized numerically. The data is organized numerically because it involves numbers and place values. Mrs. Ellwood’s brain

5. If Shaniqua’s grade has not yet been put in, what grade will she need to make the class average 93 if this is a possible grade to get? Key 8 l 5 = 85%

6. How to Create a Stem and Leaf Plot • Create a problem • Collect data pertaining to the problem • Make a big “t” • Put the greatest place value digit on the left side of the “t” in numerical order • Put the least place value digit on the right side of the “t” in numerical order

7. Advantages • Shows specific data • Organized, ordered data Dylan’s brain, Brett’s brain, and Patrick’s brain

8. Disadvantages • Data can be overloaded on one line and looks awkward. • Not informative for a small set of data http://www.slideshare.net/bujols/stem-leaf-bar-graphs-and-histograms Patrick’s brain, Dylan’s brain, and Brett’s brain
