ANALYSIS IN SCIENCE
If some of these questions are reminding you of science class, you’re not crazy. One of the “Cross-Test
scores” the SAT aims to measure is called Analysis in Science. This means that questions on science-
based ideas will show up in Reading and Writing passages and also in Math questions. That’s part of the
reason for all these charts and graphs. Many times, you will be asked if a conclusion can be reached
based on the chart. In those cases, just do as you have been throughout this chapter’carefully look up the
numbers in question, do the required calculations, and eliminate answers that aren’t true.
You may also be asked to graph the data presented in a table. Your knowledge of positive and negative
relationships from Chapter 11 will help’you can eliminate things with the wrong relationship.
