Types of DS&P Items
On the SAT, the DS&P items are one of four basic types:
 Graph(ics)
 Data Puzzlers
 No Problem with Probability
 What the #!*@?
Graph(ics)
A Graph(ics) item is any item that is accompanied by a
graph or chart. The majority of these items simply test whether
you can understand and interpret the information being presented
to you. These are the Just Read It Vanilla items we covered in the
last section. More difficult items will ask you to perform some
type of operation on the graph or chart. These are the Chunky Operations
Chocolate items.
This is what a typical Graph(ics) item looks like:


4. 
What two years had the least difference
in gross national product? 
 (A) 
1986 and 1990 
 (B) 
1986 and 1988 
 (C) 
1986 and 1987 
 (D) 
1987 and 1989 
 (E) 
1989 and 1990 

Data Puzzlers
Data Puzzler items involve sets of numbers and usually
ask about mean, median, mode, range, or any combination of them.
The reason we call them puzzlers is because the
correct answer usually requires you to find some missing piece of
information that was not asked about directly. A typical Data Puzzler
item will look a lot like this:


7. 
If
the average of 13, 6, 9, x, and y is
12, what is the average of x + y? 
 (A) 
6 
 (B) 
9 
 (C) 
12 
 (D) 
16 
 (E) 
32 

No Problem with Probability
No Problem with Probability items ask about the chances
of a certain event happening or not happening. The majority of answer
choices for this item type will be in fraction form:


9. 
If
a card is pulled at random from an ordinary 52card deck of playing cards,
what is the probability of pulling a face card (Jack, Queen, or King)? 
 (A) 

 (B) 

 (C) 

 (D) 

 (E) 


What the #!*@?
What the #!*@? items deal with factorials, permutations,
and combinations. As we already mentioned, these items almost always
appear at the end of Math sets, because they are pretty difficult.
A typical What the #!*@? looks like this:


17. 
Susanne
has eleven different medals from her two years of competitive swimming.
Unfortunately, the mounting frame she wishes to place them in has
room for only two. How many different combinations of medals can
Susanne place in her frame? 
 (A) 
21 
 (B) 
33 
 (C) 
55 
 (D) 
66 
 (E) 
110 

Each of these item types requires a different strategic
approach to solve for the right answer. Your goal is to familiarize
yourself with both the item type and the strategies that are specific
to the particular item.
