Problem-Solving and Data Analysis
Problem-Solving and Data Analysis covers roughly 15% of SAT Math: ratios, rates, percentages, proportions, units, and the statistics of tables, scatterplots, and study design. It is the most calculator-friendly and real-world domain.
What the exam asks
- Set up and solve ratio, rate, proportion, and unit-conversion problems
- Compute percent change and reverse-percentage problems
- Read two-way tables and compute conditional probabilities from them
- Interpret scatterplots, lines of best fit, and residual-style reasoning
- Compare mean, median, mode, and range, and reason about outliers and spread
- Judge sampling methods and whether conclusions about cause are justified
Key formulas and rules
(new − old) / old × 100%
a/b = c/d ⇒ ad = bc
mean = sum / count, so sum = mean × count
P(A given B) = (count in A and B) / (count in B)
outliers pull the mean, barely move the median
larger random samples ⇒ smaller margin of error

Study tip
For conditional probability from a two-way table, underline the 'given' group first and use only that row or column as your denominator — most wrong answers come from using the grand total.
