Depending on the data to be displayed, some types of graphs are more useful than others.
Example #1 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
10 11 12 13 14 15 16 17 18 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. xx x x x
#2 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
Stems Leaves 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. 1 1 1 4 2 6 7 3 5 Key 2|6 means 26.
#3 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
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.
#4 The table shows the number of tickets each student purchased for the school carnival. Which graph would be more appropriate to show the data-a line plot or line graph?
1 2 3 4 5 6 7 8 9 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. xxx x x
#5 The table shows the weights of fish caught today. Which graph would be more appropriate to show the data- a bar graph or a line plot?
