Data Analysis comes up in two of the three ACT Science passage-types: Research Summaries and Data Representation. Data can be presented in tables, charts, graphs, etc. Use these tips to rock these questions on Test Day!
The key to data analysis is fairly easy: actually take the time to analyze the data! Most people skip parts of the information and go straight to the questions, but you’ll need to know where to look for the correct answer!
Two variables are in “direct variation” with each other if the following relationship holds: whenever one variable doubles, the other variable doubles. Two variables are in “inverse variation” with each other if the following relationship holds: whenever one variable doubles, the other variable halves. Variables commonly have one of these two relationships on the ACT Science Test.
Data Analysis primarily is required for Data Representation passages, since they typically have more data than Research Summaries passages. For these, always identify the purpose, method, and the results. The data is usually in the form of the “results.”
