When reading graphs, the key is to be sure that you know exactly what the numbers on each axis represent. Otherwise, you're likely to misinterpret the information. On this bar graph, you see that the horizontal axis represents the time of day, and the vertical axis represents the number of accidents that occurred. Thus, the tallest box shows the time of day with the most accidents.     Like regular reading comprehension questions, questions on tables, charts, and graphs may also ask you to make inferences and maybe even do basic math using the information and numbers presented on the table,...

When reading graphs, the key is to be sure that you know exactly what the numbers on each axis represent. Otherwise, you're likely to misinterpret the information. On this bar graph, you see that the horizontal axis represents the time of day, and the vertical axis represents the number of accidents that occurred. Thus, the tallest box shows the time of day with the most accidents.    

Like regular reading comprehension questions, questions on tables, charts, and graphs may also ask you to make inferences and maybe even do basic math using the information and numbers presented on the table, chart, or graph.

Here you can actually see the time of the greatest number of accidents represented by a line that corresponds to the time of day and number.

These numbers can also be represented by a box in a bar graph, as follows.
