SAT Math Lesson Plan 12: Measures of Central Tendency

Lesson 12 in this SAT Math Prep series focuses on calculating and interpreting measures of central tendency, including mean, median, mode, and range. Students also learn how to compute weighted averages and analyze data sets using quartiles and interquartile range (IQR). This 45-minute lesson provides essential skills for mastering data analysis questions, which account for approximately 5–10% of the SAT Math section. The lesson includes a step-by-step Warm-Up, seven fully worked-out examples, and a Review section with additional examples and guided solutions. Real-world applications and SAT-style questions are emphasized throughout. Special attention is given to interpreting outliers and analyzing categorical data using mode, a concept often overlooked in standard prep materials. A 10-question multiple-choice quiz with detailed answer key reinforces mastery of the content. This lesson supports Common Core standards for statistics and data analysis and helps students build confidence with one of the most testable areas in SAT Math.
