. Periodicity
the tendency of a function to repeat itself in a regular pattern at established intervals.
Permutation
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
the chance of an event happening, usually expressed as the ratio of the number of favorable outcomes to
the total number of outcomes
Proportion
a statement that two ratios (or fractions) are equal
Rate of change
the change in the value of a quantity divided by the elapsed time
Scientific notation
a number written as the product of a number between 1 and 10 and a power of 10
Standard deviation
a measure of how spread out numbers are
Table
an organized chart or list of numbers
Unit rate
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
comparison between two numbers. Separated by a colon (:), the word "to", or may be written in fraction
form.
Proportion
an equation that shows that two ratios are equal. Numbers may change in value, but will keep the same
proportional relationship to one another.
Cross Products
Box plot
, a way of graphically depicting groups of numerical data through their quartiles
Consecutive
one following the other, for example, 19 and 20 are consecutive numbers
Data
a collection of facts, such as numbers, words, measurements, observations or even just descriptions of
things
Dot plot
a graphical display of data using dots
Event
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
how often something happens (usually during a period of time)
Function
a special relationship where each input has a single output. It is often written as "f(x)" where x is the input
value
Graph
a diagram that shows a relationship among numbers
Histogram
a graphical representation of the distribution of numerical data
Matrix
a rectangular array of numbers or other mathematical objects, for which operations such as addition and
multiplication are defined.
Mean
the sum of a set of numbers divided by the number of numbers in a set (AKA average)
Median
a number in the middle of a set of numbers, or the mean of the two middle numbers in a set
Mode
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
