For questions involving Data Analysis:

Be sure you know how to calculate:

permutations and combinations

probabilities of events, including compound and independent events

range, mean, median, and mode

quartiles, interquartile range, percentiles, and standard deviation

simple and compound interest

Be sure you know how to interpret the various visual presentations of data:

diagrams and figures

tables and forms

line graphs, bar graphs, pictographs, and scatterplots

pie charts (circle graphs)

boxplots, histograms, and frequency distributions

Remember:

Pay special attention to titles, headers, labels, units, and legends.

For tables, determine exactly what the rows and columns represent, and note any missing

values in empty fields.

For graphs, determine exactly what the axes represent, and note the values at the origin.

Know the approximate probability percentages within the subdivisions of the normal

distribution.

For Multiple-Choicequestions with only one correct answer choice (ovals):

Again, use the process of elimination to improve your chances of guessing correctly:

If all of the answer choices are definitely incorrect, then the remaining answer choice

must be correct!

For Multiple-Choicequestions with one or more correct answer choices (checkboxes):

Again, use the process of elimination to improve your chances of guessing correctly:

For these kinds of questions, you must choose all the correct answer choices, and none of

the incorrect ones. Theres no credit for an answer that is partially correct.

Be sure you follow any instructions that indicate the number of correct answer choices

(e.g., Indicate both such values means you must select exactly two answer choices).

For Numeric Entryquestions:

Be sure your entries answer the questions precisely! Verify that:

Your entries are the exact values that have been requested.

Your entries are in the proper units.

Any fractional entries have been entered into the appropriate numerator and denomina-

tor boxes.

Remember:

To make an entry negative, type a hyphen (-).

For Quantitative Comparisonquestions:

Treat the columns as if they were sides of an equation or inequality. You can:

Add or subtract like terms on each side. Multiply or divide by common positivefactors on each side.

Remember:

Exact values arent usually necessary! You just have to compare the two quantities.

Sometimes simply determining the sign and/or range of each quantity is enough.

If the relationship between the two quantities can vary, then the answer must be the

fourth choice (i.e., the relationship cannot be determined from the information given).
