GED Math Exam Questions and Answers
Graded A+
Box plot - Correct answer-a way of graphically depicting groups of numerical data
through their quartiles
Consecutive - Correct answer-one following the other, for example, 19 and 20 are
consecutive numbers
Data - Correct answer-a collection of facts, such as numbers, words,
measurements, observations or even just descriptions of things
Dot plot - Correct answer-a graphical display of data using dots
Event - Correct answer-a set of possible outcomes resulting from a particular
experiment. For example, a possible event when a single six-sided die is rolled is
{5, 6}. That is, the roll could be a 5 or a 6.
Frequency - Correct answer-how often something happens (usually during a period
of time)
Function - Correct 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 - Correct answer-a diagram that shows a relationship among numbers
Histogram - Correct answer-a graphical representation of the distribution of
numerical data
Matrix - Correct answer-a rectangular array of numbers or other mathematical
objects, for which operations such as addition and multiplication are defined.
Mean - Correct answer-the sum of a set of numbers divided by the number of
numbers in a set (AKA average)
Median - Correct answer-a number in the middle of a set of numbers, or the mean
of the two middle numbers in a set
Mode - Correct 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.
Periodicity - Correct answer-the tendency of a function to repeat itself in a regular
pattern at established intervals.
Permutation - Correct 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 - Correct 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 - Correct answer-a statement that two ratios (or fractions) are equal
Rate of change - Correct answer-the change in the value of a quantity divided by
the elapsed time
Scientific notation - Correct answer-a number written as the product of a number
between 1 and 10 and a power of 10
Standard deviation - Correct answer-a measure of how spread out numbers are
Table - Correct answer-an organized chart or list of numbers
Unit rate - Correct 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 - Correct answer-comparison between two numbers. Separated by a colon (:),
the word "to", or may be written in fraction form.
Proportion - Correct answer-an equation that shows that two ratios are equal.
Numbers may change in value, but will keep the same proportional relationship to
one another.
