GED MATH EXAM COMPREHENSIVE
MATHEMATICS STUDY GUIDE 2026
◉ Consecutive.
Answer: one following the other, for example, 19 and 20 are
consecutive numbers
◉ 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
◉ Event.
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.
Answer: how often something happens (usually during a period of
time)
,◉ 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
◉ Matrix.
Answer: a rectangular array of numbers or other mathematical
objects, for which operations such as addition and multiplication are
defined.
◉ 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.
◉ Periodicity.
Answer: the tendency of a function to repeat itself in a regular
pattern at established intervals.
◉ 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
◉ Rate of change.
Answer: the change in the value of a quantity divided by the elapsed
time
◉ Scientific notation.
Answer: a number written as the product of a number between 1
and 10 and a power of 10
◉ Standard deviation.
Answer: a measure of how spread out numbers are
◉ Table.
Answer: an organized chart or list of numbers
◉ 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.
