The Data Representation format on the ACT Science Test will ask you to understand and interpret information presented to you in graphs or tables. Occasionally there will also be charts, scatterplots, and diagrams.

As the video below outlines, it’s important to REALLY analyze all the data you’re given. The point of Data Rep is to determine your ability to pinpoint and extract conclusions from a series of data. 38% of the ACT Science passages will be in this format.

Making sure you have a strong understanding of the data will save you lots of headache when you read the questions. The questions will be so much easier if you spend just a few minutes focusing on the data. Check out tutor Jim Jacobson’s strategy for just how to do that in this video!

Need to see a passage in action? Sparknotes reviews some basic strategy, then shows you a passage exactly like one you’ll see on Test Day. Start with the intro, then when you get to the chart, you should glance over it to make sure that you know what’s being measured and that, in general, you feel comfortable finding information in the chart.
