You’ll see a number of different diagram types soon enough, but turn the page to get us started. Take a quick scan through this one, but don’t worry about answering the question just yet; we’ll come back to it later on.

Directions: The question below refers to the following graph. Select the best of the answer choices given.

In which of the following years was the number of new homes built with a wood exterior less than the number of new homes built with a siding exterior?
(A) 1940
(B) 1950
(C) 1960
(D) 1970
(E) 1980
You’ll probably see two distinct sets of DI questions on your test, each consisting of two questions. That is, if a graph like the one above appears in the first DI set, you’ll answer two questions based on it. Then, after some Problem Solving and Quantitative Comparison problems, another DI set will appear with new diagrams and another two questions, which combined makes for four DI questions total.
The DI example above has only one diagram, although a set may contain two or even three diagrams. In this case, the diagram is a bar graph. Other kinds of diagrams include circle graphs, line graphs, and tables. The graph will appear on the left side of the screen while the questions appear on the right (one at a time). If the graph and any accompanying information don’t fit on the screen, they will appear in a scroll box, much like the longer Reading Comprehension passages you’ll see in the Verbal section. The directions are standard fare for multiple-choice questions: Choose the best answer out of the five provided.
