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

Percent change

(new − old) / old × 100%

Proportion

a/b = c/d ⇒ ad = bc

Average

mean = sum / count, so sum = mean × count

Probability from a table

P(A given B) = (count in A and B) / (count in B)

Outlier effects

outliers pull the mean, barely move the median

Margin of error

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.
