GED MATH COMPREHENSIVE EXAM STUDY
GUIDE WITH COMPLETE SOLUTIONS
●● consecutive numbers
Answer: numbers in counting order
●● Data
Answer: a collection of facts, such as numbers, words, measurements,
observations or even just descriptions of things
●● Dot plot
Answer: a graphical display of data using dots
●● Function
Answer: a special relationship where each input has a single output. It is
often written as "f(x)" where x is the input value
●● Graph
Answer: a diagram that shows a relationship among numbers
●● Histogram
Answer: a graphical representation of the distribution of numerical data
,●● Mean
Answer: the sum of a set of numbers divided by the number of numbers
in a set (AKA average)
●● Median
Answer: a number in the middle of a set of numbers, or the mean of the
two middle numbers in a set
●● Mode
Answer: The mode of a set of numbers is the one that occurs most often.
So, in the set {1,5,7,5,9}, the mode is 5 because there are 2 fives and
only one of each of the others.
●● Permutation
Answer: relates to the act of rearranging, or permuting, all the members
of a set into some sequence or order (unlike combinations, which are
selections of some members of the set where order is disregarded)
●● Probability
Answer: the chance of an event happening, usually expressed as the ratio
of the number of favorable outcomes to the total number of outcomes
●● Proportion
,Answer: a statement that two ratios (or fractions) are equal
●● Scientific notation
Answer: a number written as the product of a number between 1 and 10
and a power of 10
●● Unit rate
Answer: describes how many units of the first type of quantity
corresponds to one unit of the second type of quantity. Some common
unit rates are miles (or kilometers) per hour, cost per item, earnings per
week, etc.
●● Ratio
Answer: comparison between two numbers. Separated by a colon (:), the
word "to", or may be written in fraction form.
●● Cross Products
Answer: The product of the numbers which are diagonal from one
another in a proportion equation. Should be equal on both sides.
●● Common denominator
Answer: for a set of fractions, a number into which each denominator
can divide evenly
, ●● Denominator
Answer: the bottom number in a fraction
●● Difference
Answer: the answer to a subtraction problem
●● Digit
Answer: one of the ten number symbols. The digits are 0, 1, 2, 3, 4, 5, 6,
7, 8, and 9.
●● Equation
Answer: a statement that two amounts are equal
●● Estimate
Answer: as a noun: an approximate value.
as a verb: to find an approximate value.
●● Fraction
Answer: a part of a whole
●● Greatest common factor
Answer: the greatest factor that divides two numbers
