| Half-life |
The
length of time needed for a value to decrease to half of its original
amount. This term often refers to the decay of a radioactive material. |

A
bar graph in which the length of the bars shows the frequency of data
values. |
| horizontal axis |
left-to-right
number line on a graph |
| Horizontal axis |
Horizontal
lines that run from top to bottom that forms a graph. |
| Imaginary
number |
The
square root of a negative number. |
| improper fraction |
a
fraction greater than one or equal to one |
| Independent
variable |
In
a function of two variables, one variable is dependent and the other
independent. |
| Inductive
reasoning |
Reaching
a conclusion on the basis of patterns found in a number of observations. |
| Integers |
A
whole number that can be positive or negative. |
| Interquartile
range |
The
difference between the lower (first) and upper (third) quartiles (the
length of the box in a box plot). |
| Irrational
number |
A
number whose decimal expansion is non-repeating and nonterminating, for
example, 2 and pi. |
| Isosceles triangle |
A
triangle with two equal sides. |
| least common denominator |
the
least common multiple of the denominators of two or more fractions |
| Least-squares
line |
A
best-fit line determined by calculating the line with the minimum sum of
the squares of the residuals. |
| Limit |
A
central concept of calculus indicating a number that a sequence of numbers
approaches. A value a function approaches but never attains. |
| Limiting
value |
The
long-run value of a sequence or a series. The value as n grows infinitely
large. |
| line graph |
uses
a drawn line to show increases and decreases over time |
| Line of
symmetry |
A
line that divides a graph into two common congruent pieces. If the graph
could be folded along this line, the two halves would lie directly on top
of each other. |
| line plot |
uses
symbols above a number line to show data |
| Line Plot |
A way to organize numerical data; shows the range of data and how
the data are distributed over that range. |
| Linear |
Having
to do with a line, a first-degree expression, a first-degree equation, or
a first-degree polynomial. |
| Linear
function |
A
function that can be expressed in the form of a linear equation (an
equation in which a variable is raised to the first power). |
| Linear measurement |
The
measurement of a line. For
example length, width and height are linear measurements of a box. |
| Logarithm |
In
the equation a = bx, the logarithm base b of a provides the value of the
exponent, log ba = x. The logarithm is the exponent for b to give the
value a. |
| Mathematical
model |
An
equation or rule that describes a relationship that closely fits a set of
data. |
| Matrix |
A
rectangular array of numbers. The dimensions of a matrix are specified by
the number of rows and columns it contains. A 2 x 3 matrix contains 2 rows
and 3 columns. |
| Maximum
value |
The
highest (largest, greatest) value. |
| Mean |
The
average value calculated as the sum of all the values divided by the
number of values in the set. |
| mean |
an
average calculated by adding up all the data values and dividing by the
number of values |
| Measure
of central tendency |
A
single value used to characterize or represent an entire set. Examples
include the mean, the median, and the mode. |
| Median |
The middle number of an ordered set. If the set has an even
number of values, then the median is the average of the two middle values. |
| median |
the middle value when all data are arranged in order from
smallest to largest |
| Median |
The number in the middle of a group of numbers arranged in
order from least to greatest. |
| mixed
number |
a number that has a whole
number and a fraction |
| mode |
the number that occurs most
often |
| Mode |
The value that occurs most frequently in a set. |
| mode |
the most frequent value in a data set; the highest point on
a frequency graph |
| MORE |
add; increase |
| Multiple |
Numbers formed by multiplying a number by a whole number.
The multiples of 3 are 0, 3, 6, 9, 12, 15 etc. |
| Multiple
Tower |
A tower built by listing the multiples of a particular
number until the tower is as tall as the person building it. |
