A. 16, 5, 31, 14, 14, 18 mean: the values Divide by, the number of values. median: values 3 values the values. the two middle values. mode: The value occurs two times. 7 Holt Pre-Algebra
7 LESSON 4-3 CONTINUED B. 83, 45, 19, 33 mean: the values. 180 Divide by, the number of values. median: values values the values. Average the two values. mode: other. occurs more than any Try This 1. Find the mean, median, and mode of the data set. 4, 31, 1, 18, 4, 73 Holt Pre-Algebra
8 LESSON 4-4 Variability pp Vocabulary variability (p. 188) range (p. 188) quartile (p. 188) box-and-whisker plot (p. 189) Additional Examples Example Use the given data to make a box-and-whisker plot. 1, 5, 15, 13, 17, 19, 19, 1 Step 1. Order the data and find the smallest value, first quartile, median, third quartile, and largest value. smallest value: first quartile: median: third quartile: 74 Holt Pre-Algebra
9 LESSON 4-4 CONTINUED largest value: Step. Draw a number line and plot a point above each value from Step Step 3. Draw the box and whiskers Try This 1. Find the range and the first and third quartiles for the data set. 45, 31, 59, 49, 49, 69, 33, 47. Use the given data to make a box-and-whisker plot. 31, 3, 33, 35, 6, 4, 31, Holt Pre-Algebra
10 LESSON 4-5 Displaying Data pp Vocabulary bar graph (p. 196) frequency table (p. 196) histogram (p. 196) line graph (p. 197) Additional Examples Example 1 Organize the data into a frequency table and make a bar graph. The following data set reflects the number of hours of television watched every day by members of a sixth-grade class: First, organize the data into a table. The times each value occurs. is the number of Television Viewing by Sixth-Graders The frequencies are the the bars in the bar graph. of 76 Holt Pre-Algebra
11 LESSON 4-5 CONTINUED Example Jimmy surveyed 1 children to find out how much money they received from the tooth fairy. Use the data to make a histogram First, make a intervals of $1.00. Then make a table with Money Given by the Tooth Fairy. Example 3 Make a line graph of the given data. Use the graph to estimate Mr. Yi s salary in 199. Create ordered pairs from the data in the table and plot them on a grid. Connect the points with lines. You can estimate the salary in 199 by finding the point on the line between 1990 and 1995 that corresponds to 199. Year Salary ($) , , , ,000 Mr. Yi s Salary Mr. Yi s 199 salary was about $. 77 Holt Pre-Algebra
