Use a bar graph to display and compare data. Use a line graph to show how data change over a time period. Use a circle graph to show how a set of data is divided into parts.

Example 1: Choosing and Creating an Appropriate Display Use the given data to make a graph. Explain why you chose that type of graph. Step 1 Choose an appropriate scale and interval. The scale must include all of the data values. Flowers in an Arrangement

Example 1: Choosing and Creating an Appropriate Display Use the given data to make a graph. Explain why you chose that type of graph. A bar graph is good for displaying categories that do not make up a whole. Step 1 Choose an appropriate scale and interval. The scale must include all of the data values. Flowers in an Arrangement

Example 1 Continued Step 2 Use the data to determine the lengths of the bars. Draw bars of equal width. The bars should not touch. Step 3 Title the graph and label the horizontal and vertical scales.

Example 3: Choosing and Creating an Appropriate Display Use the given data to make a graph. Explain why you chose that type of graph. Step 1 Determine the scale and interval for each set of data. Time should be plotted on the horizontal axis because it is independent. County Farms 248

Example 3: Choosing and Creating an Appropriate Display Use the given data to make a graph. Explain why you chose that type of graph. A line graph is appropriate for this data because it will show the change over time. Step 1 Determine the scale and interval for each set of data. Time should be plotted on the horizontal axis because it is independent. County Farms 248
