How to Analyze a Graph
1. Read the title and the axes of a graph to determine the information included.
The x-axis is the line on a graph that runs horizontally (left to right), and the y-axis is the line that runs
vertically (up and down). For example, in Figure 1-10, different healthcare occupations are listed along
the y-axis, and projected job opportunities (in hundreds of thousands) are listed on the x-axis. Based on
your interpretation of this information, how many positions did the Bureau of Labor Statistics project for
medical assistants?
2. Determine the general trend of the graph.
For example, if you review the growth chart graph of a 2-year-old girl, you would be able to see whether
her height and weight have consistently increased over time or whether she has had a sudden increase
(maybe a growth spurt) or a decrease that might reflect a recent illness.
3. Graphs can also be useful in visualizing information that doesn't seem to fit.
For example, if you are responsible for measuring the length and weight of a 4-month-old infant and the
measurements that you took are markedly different (either larger or smaller) than the measurements
recorded at the last well-child examination, perhaps your measurements are incorrect. If you check
them again and come up with the same numbers, document your results but inform the provider of the
differences so the provider can investigate the changes with the baby's caregiver. Can you see how
being able to use graphs can help you gain insight into patient healthcare results?
