Stem and Leaf Plots Examples
1. A stem and leaf plot is a method used to organize statistical data. The greatest common place value of the data is used to form the stem. The next greatest common place value is used to form the leaves. 17 stem leaf
2. EXAMPLE: Make a stem and leaf plot of the algebra test scores given below. Then complete each question. 56, 65, 98, 82, 64, 71, 78, 77, 86, 95, 91, 59, 69, 70, 80, 92, 76, 82, 85, 91, 92, 99, 73 1st put the scores in numerical order.
56, 59, 64, 65, 69, 70, 71, 73, 76, 77, 78, 80, 82, 82, 85, 86, 91, 91, 92, 92, 95, 98, 99
Since the data range from 56 to 99, the stems range from 5 to 9. To plot the data, make a vertical list of the stems. Each number is assigned to the graph by pairing the units digit, or leaf, with the correct stem. The score 56 is plotted by placing the units digit, 6, to the right of stem 5.
Stem 5 6 7 8 9
Leaf 69 459 013678 02256 1122589
a. What type of graph does a stem and leaf plot represent when turned vertically? Histogram b. What was the lowest score on the algebra test? 56 c. What was the highest score on the algebra test? 99 d. In which interval did most students score? 90 to 99
