Problem-Solving & Data Analysis

Ratios, rates, percentages and reading quantitative claims out of tables and graphs.

• Conditional probability & two-way tables A two-way table is a reading problem dressed as arithmetic. 12 questions · 3 worked examples
• Evaluating statistical claims This skill is vocabulary wearing a data costume. 12 questions · 3 worked examples
• Inference from sample data A sample hands you one number — a percent, a mean, a count — and a margin of error. 12 questions · 3 worked examples
• One-variable data (center & spread) A whole column of the test hands you one variable drawn as a picture — a dot plot, a histogram, a box plot, a frequency table — and asks a question you answer by counting, not by calculating. 12 questions · 3 worked examples · 5 figures
• Percent growth/decay in context A percent sentence becomes a multiplier, then a model. 12 questions · 3 worked examples
• Percentages Nothing here is hard arithmetic. 12 questions · 3 worked examples
• Probability On the Digital SAT, probability is almost never a formula hunt. 12 questions · 3 worked examples
• Ratios, rates & proportions A ratio item hands you a comparison and asks you to carry it to a different size. 12 questions · 3 worked examples · 2 figures
• Two-variable data (scatterplots & models) A scatterplot puts two numbers on every subject — a tree's age and its harvest, a stop's length and its checkouts — and then the test draws a line through the cloud and asks about the line. 12 questions · 3 worked examples · 5 figures
• Units & conversions A conversion item is one multiplication chain. 12 questions · 3 worked examples
