Mathematics SAT-68: Triangles — Interior and Exterior Angle Theorems Use the 180° interior-angle sum and the exterior-angle theorem to find unknown triangle angles.
Mathematics SAT-67: Parallel Lines Cut by a Transversal Find every angle when a transversal crosses parallel lines using corresponding and alternate angles.
Mathematics SAT-66: Lines and Angles — Vertical, Supplementary, and Complementary Use vertical, supplementary (180°), and complementary (90°) angle relationships to solve for unknowns.
Mathematics SAT-65: Linear vs. Exponential Data Modeling Choose the right model for real data — linear for constant change, exponential for constant percent change.
Mathematics SAT-64: Comparing Data Sets — Boxplots and Histograms Read the five-number summary from a boxplot and shape from a histogram, then compare two data sets.
Mathematics SAT-63: Margin of Error and Confidence Intervals Interpret a margin of error and a confidence interval, and know what raises or lowers the margin.
Mathematics SAT-62: Experimental Design — Random Assignment and Cause-and-Effect Tell experiments from observational studies and know when you can claim one thing causes another.
Mathematics SAT-61: Selection Bias and Generalizing Results Spot selection bias, judge when results generalize, and decide which population a conclusion applies to.
Mathematics SAT-60: Sample Surveys and Random Sampling Understand populations vs samples and why random sampling is required to draw valid conclusions.
Mathematics SAT-59: Conditional Probability from Two-Way Tables Read two-way frequency tables and compute conditional probabilities by restricting to the given group.
Mathematics SAT-58: Probability — Simple and Independent Events Find the probability of simple events and combine independent events by multiplying.
Mathematics SAT-57: Standard Deviation — Measuring Data Spread Understand standard deviation as a measure of spread and compare data sets without heavy calculation.
