READ AND INTERPRET GRAPHS A graph is a diagram that shows information in an organized way. Each axis is labeled to identify the data being presented. There are several types of graphs: bar graphs, line graphs, picture graphs, and circle graphs. All serve the same purpose: to organize data. Graphs show relationships between two numbers and also compare two or more sets of data In the bar graph, the number of fish caught in 2006 is compared with the number of fish caught in 2007. This graph also illustrates a comparison between the kinds of fish that were caught. The labels on the graph help us read and interpret the graph. We read the facts shown and we also make inferences and draw conclusions as we interpret the meaning of the data presented on the graph. © Copyright NewPath Learning. All Rights Reserved.

How to read and interpret graphs: Begin by reading the labels in order to understand what data is being presented. Use the horizontal axis and the vertical axis to “read” the graph. In the graph #1 above, 60 trout were caught in 2006, 75 perch were caught in 2007, 30 salmon were caught in 2007, and 10 bass were caught in 2007. By reviewing the graph, you can also interpret the data. This includes making inferences and drawing conclusions. For instance, a conclusion might be more walleye were caught in 2007 than in 2006. An inference might be there were more walleye to catch in 2007. In the picture graph, the number of fruit needed to make a pie is graphed using a “fruit shape.” Each picture of the fruit is equal to 2. From reading the graph, you can conclude 14 peaches are needed to make a pie. You can infer that cherries must be smaller than apples since it takes so many more of them to make a pie. © Copyright NewPath Learning. All Rights Reserved.
