# SAT Secret 28: The SAT Math Test: Problem Solving and Data Analysis

### 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:

• Convert units (for example changing km/hr to meters/second)
• Choose appropriate graphical representations for data sets
• Interpret the slope and intercepts of a line
• Compute and interpret probability
• Evaluate statistical claims or the results of a study
• Use percentages in a variety of contexts, including discounts, interest rates, taxes, and tips [Explain]Ok, so 299 is the sale price, which is the wholesale price (WP) plus 15%. Calculate WP by creating an equation: 299 = 1.15(WP) – this says that 299 is 115% of the WP. From this, we find that the WP is 260. Find 75% of the WP and add it on, and you get \$455 (B).
