Course 3
9-2 Organizing Data
Organizing raw data can help you see patterns and trends. One way to organize data is to use a line plot. A line plot uses a number line to show how often a value occurs in a data set.
![Page 7: 9-2 Organizing Data Course 3 Warm Up Warm Up Problem of the Day Problem of the Day Lesson Presentation Lesson Presentation](https://reader030.vdocuments.net/reader030/viewer/2022032709/56649ed05503460f94bdef06/html5/thumbnails/7.jpg)
Course 3
9-2 Organizing Data
Additional Example 1: Organizing Data in Line Plots
Use a line plot to organize the math exam scores.
Find the least value, 50, and the greatest value, 100, in the data set. Then draw a number line from 50 to 100. Place an “x” above each number on the number line for each time it appears in the data set.
Student Test Scores

90 85 80 100

A stem-and-leaf plot is another way to display data. The values are grouped so that all but the last digit is the same in each category.
Stem = first digits(s)
Leaf = last digit
2 5 = 25

A back-to-back stem-and-leaf plot is used to compare two sets of data. The stems are in the center, and the left leaves are read in reverse.
