Mathematics SAT-55: Descriptive Statistics — Mean and Median Compute and compare the mean and median, work backward from a known mean, and know which is better with skewed data.
Mathematics SAT-54: Scatterplots — Lines of Best Fit and Trends Read scatterplots, describe correlation, and use a line of best fit to estimate and predict values.
Mathematics SAT-53: Interpreting Tables, Graphs, and Bar Charts Read values, totals, and trends from tables, line graphs, and bar charts — and avoid common reading traps.
Mathematics SAT-52: Percent Change — Increase, Decrease, and Successive Changes Compute percent increase/decrease, use multipliers, and chain successive percent changes correctly.
Mathematics SAT-51: Percentages — Part, Whole, and Base Master the part = percent × whole relationship to find a part, a whole, or a percent.
