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)
Do not perform more calculations than are necessary
Compare quantities in parts

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

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!

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

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

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)
