How to Read Graphs

Being successful on your GED® Science test is, in large part, determined by the answer to one single question: Are you, as a test-taker, able to read charts or tables?

This hugely important because, with data representations, test-takers who can’t read the table or graph may never even get around it to the text.

So with graphs, the key questions that students need to deal with are answering things such as “what exactly is an x-axis label? What exactly is a y-axis label? Are there other labels? Are there any keys? What relationship have the x-axis and the y-axis?”

Now, axes are those lines at the bottom of the side(s) of a graph. Axes may be very useful for figuring out the variable(s) and the control in, for example, an experiment.

By definition, graphs come with x-axes and y-axes. X-axes are the horizontal lines, usually at the graph’s bottom. Y-axes are the vertical lines, usually placed on the graph’s left side.

On the GED Science test, graphs may present or indicate units of measure for one of the axes next to the labels.

Don’t even try to grasp what those units are meaning. Often, GED Science questions are throwing in some weird, crazy, units that no test-taker will have ever seen unless they studied at a very high level.

In Physics and Chemistry, there’s no need for you to understand what they stand for to find the correct answers to the questions.

There’s absolutely no need to dwell on these units or get all-stressed over them.
