Depending on the data to be displayed, some types of graphs are more useful than others.

Common Uses of Data Displays

Line Plot

You can use a line plot to show the

frequency of values on a number line.

Bar Graph

You can use a bar graph to display

and compare data in separate categories.

Line Graph

You can use a line to show how data

change over a period of time.

Stem-and-Leaf

You can use a stem-and-leaf plot to show how often data values occur and how they are

distributed.

A table shows the miles jogged by five boxers. Which graph would be more appropriate to show the data-a line plot or a line graph? Defend your answer

Boxer Al Bo Max Jo TyMiles 12 17 10 18 17

Example #1

Think: is the information in the table describing the frequency of values? Is it describing a

change over time?

A line plot table shows the frequency of values on a number line. So a line plot table is more appropriate than a line graph table.

The table shows the height of some plants. Which graph would be more appropriate to show the data-a bar graph or a stem-and-leaf plot? Defend your answer

Height of Plants (ft)11 27 14 35 11 26

#2

Think: The table shows a number of different heights. It does not compare data in separate

categories.

A stem-and-leaf plot shows how often data values occur. So a stem-and-leaf plot is more appropriate than a bar graph.

Key 2|6 means 26.

A table shows the number of feet of grass each neighbor must mow. Which graph would be more appropriate to show the data-a line graph or bar graph? Defend your answer

Neighbor Sal Jax Pete Lar NiFeet 32 11 5 25 20

#3

Think: is the information in the table describing a change over time? Is the information in the

table divided into different categories?

The table shows the number of feet each neighbor mows. The data should be displayed in separate categories. So a bar graph is more appropriate than a line graph. 0

#4

Think: is the information in the table describing the frequency of values? Is it describing a

change over time?

A line plot shows the frequency of values on a number line. So a line plot is more appropriate than a line graph.
