Data representation questions

On the GED Science test, there are three types of passages.

It is crucial that you understand and know what those passages are, how to identify these passages, so you can manage the test from a time management perspective.

So that’s what we’ll be covering now.

Your GED Science test will come with two or three passages that include data representation question.

And basically, all data representations will be focused on graphs, charts, and tables.

Once you understand and identify that a section is actually a data representation passage, the first thing to do is read the graphs and charts. Just skip the text of the passage and go straight away to the questions.

This makes sense as more than 90% of the data representation questions can be answered correctly if you learn the information that’s provided in the graphs, charts, and infographics.

What follows here is a good example of a question on data representation that we can answer already by solely looking at Figure 2.

The question here even tells us where to look. It actually says:
“According to our figure 2, the intensity of solar radiation 8 thousand years ago, was the closest to which of these following.
a. 490 watts/m2
b. 495 watts/m2
c. 500 watts/m2
d. 505 watts/m2”
So we are basically just asked to read the graph.

The graph’s x-axis is describing thousands of years ago. So what we’re looking for is 5, 6, 7, 8, thousand years ago. When we follow this line with our eyes, we’ll see that this line is intersecting with this point around here which is closest to the 500 watts per meter squared mark.

To be able to answer this question correctly, we won’t need to understand or know what exactly solar radiation intensity stands for or is and we also don’t have to know what exactly watts per meter squared is or represents.
We also are even not required to know what the words “thousands of years ago” mean. The only thing we need to do is being able to read the presenter charter graph.

So even if we don’t have the knowledge or the background information, we can relatively easily find the correct answer by following the points and lines on the graph.

So with this question, we have found the point that reads 500 watts per meter square, and that is corresponding to 8 thousand years ago.
