GED Math Questions and
Answers
Box plot
Ans- a way of graphically depicting groups of numerical data through their
quartiles
consecutive numbers
Ans- numbers in counting order
Data
Ans- a collection of facts, such as numbers, words, measurements,
observations or even just descriptions of things
Dot plot
,Ans- a graphical display of data using dots
Function
Ans- a special relationship where each input has a single output. It is often
written as "f(x)" where x is the input value
Graph
Ans- a diagram that shows a relationship among numbers
Histogram
Ans- a graphical representation of the distribution of numerical data
Mean
Ans- the sum of a set of numbers divided by the number of numbers in a set
(AKA average)
Median
,Ans- a number in the middle of a set of numbers, or the mean of the two
middle numbers in a set
Mode
Ans- 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
Ans- 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
Ans- the chance of an event happening, usually expressed as the ratio of the
number of favorable outcomes to the total number of outcomes
Proportion
, Ans- a statement that two ratios (or fractions) are equal
Scientific notation
Ans- a number written as the product of a number between 1 and 10 and a
power of 10
Unit rate
Ans- 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
Ans- comparison between two numbers. Separated by a colon (:), the word "to",
or may be written in fraction form.
Cross Products
Ans- The product of the numbers which are diagonal from one another in a
proportion equation. Should be equal on both sides.
