4. Quantitative Comparison Flashcards • The first 7-9 questions of each math section will be QC questions • Allot approximately 1¼ to 1½ minutes per question • Given Quantity A and Quantity B • Compare the two quantities and choose: A if Quantity A is greater B if Quantity B is greater C if the two quantities are equal D the relationship cannot be determined from the information given (watch the entire video here)

5. Do not perform more calculations than are necessary Compare quantities in parts      area 25 3 25 75       “bigger than” 1 2 2 A B A B   QC Strategy - Approximation Techniques Quantitative Comparison Flashcards (watch the entire video here)

6. QC Strategy - Matching Operations • Add any value to both quantities • Subtract any value from both quantities • Multiply both quantities by a positive value • Divide both quantities by a positive value Do not multiply or divide both quantities by a variable unless you are certain that the variable has a positive value Acceptable operations Quantitative Comparison Flashcards (watch the entire video here)

7. QC Strategy - Plugging in Numbers 1 1 "Nice" numbers: 0, 1, -1, , - , 10, -10 2 2 Variable(s) in the quantities consider plugging in values Drawback Without two contradictory results, you cannot be certain of the correct answer Benefit You can quickly narrow the answer choices down to two options • great for questions where you don’t know how to proceed!

9. • Some Quantitative Comparison questions can be solved quickly by applying some number sense QC Strategy – Number Sense Quantitative Comparison Flashcards (watch the entire video here)

10. QC Strategy - Miscellaneous Tips • Avoid making unnecessary computations • Do not select D if the comparison does not contain unknown values • Geometry figures are not necessarily drawn to scale (unless stated otherwise) • Pay close attention to the shared information Quantitative Comparison Flashcards (watch the entire video here)

150. Features of Normal Distributions • Data are reasonably symmetrical about the mean • Mean, median and mode are all nearly equal • About 68% of the data are within 1 standard deviation of the mean • About 95% of the data are within 2 standard deviations of the mean • About 99% of the data are within 3 standard deviations of the mean • The greater the standard deviation, the wider the curve Statistics Flashcards (watch the entire video here)

151. 1) Rearrange values in ascending order 2) The median of all values is the 2nd quartile (Q2) 3) The median of the “lesser numbers” is the 1st quartile (Q1) 4) The median of the “greater numbers” is the 3rd quartile (Q3) Least value (L) Greatest value (G) 1st Quartile (Q1) Median (M) 2nd Quartile (Q2) 3rd Quartile (Q3) Creating a Boxplot Exclude Q2 from the lesser and greater numbers Statistics Flashcards (watch the entire video here)
