The SAT Math Test: Problem Solving and Data Analysis

In this series of articles, we take a closer look at the SAT Math Test.

SAT Math questions fall into different categories called "domains." One of these domains is Problem Solving and Data Analysis.

You will not need to know domain names for the test; domains are a way for the College Board to break down your math score into helpful subscores on your score report.

Problem Solving and Data Analysis questions might ask you to create an appropriate equation from a word problem, convert units, or understand the meaning of different numbers or variables in an equation. You might need to use the different properties of operations (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction = PEMDAS).

Problems in this category may require you to use ratios, rates, and proportions. In college and beyond, you will need to interpret and synthesize data, so these are skills that are well worth developing!

Just a few examples of problems you will be asked to solve:

Converting units (for example changing km/hr to meters/second)
Choosing appropriate graphical representations for data sets
Interpreting the slope and intercepts of a line
Computing and interpreting probability
Evaluating statistical claims or the results of a study

Using percentages in a variety of contexts, including discounts, interest rates, taxes, and tips
