Data Interpretation
Following that heavy-duty QC workout, you’ll be happy to know that Data Interpretation (DI) questions require much less rigorous math than either of the math question types covered in the previous two chapters. No Pythagorean theorem, no exponents, no quadratic equations—these things simply have no place in DI. As the name implies, these questions concern data: numbers, figures, percentages, ratios, and so on. The data is contained in one or more diagrams. Your job is to find the relevant data for each question and, in most cases, manipulate it to arrive at an answer. Occasionally, you’ll need to determine that not enough information is provided to answer the question asked. There are usually four DI questions in the GRE Math section. This chapter will give you what you need to approach this question type with confidence.
As always, let’s begin with an X-ray.
