5-frame
List of all individuals w/I a population.
absolute value
The distance a number is from zero on a number line
annual
occurring or payable every year
associative property
Changing the grouping of numbers will NOT change the value. For example: (7 + 4) + 8 = 7 + (4 + 8) also works with multiplication
box and whisker plot
A graph that displays the highest and lowest quarters of data as whiskers, the middle two quarters of the data as a box, and the median
center
a point equidistant from the ends of a line or the extremities of a figure
constant
a quantity that does not vary
distributive property
a(b+c)=ab+ac
edge
a sharp side formed by the intersection of two surfaces of an object
equilateral
having all sides or faces equal
experimental probability
Probability based on data from repeating an event (doing an experiment)
frequency table
a table that lists items together according to the number of times, or frequency, that the items occur
interest
a fixed charge for borrowing money
isosceles triangle
a triangle with two equal sides
median

A way to write numbers using the digits 0-9 EX. 3,890
stem and leaf plot
A method of graphing a collection of numbers by placing the "stem" digits (or initial digits) in one column and the "leaf" digits (or remaining digits) out to the right.
theoretical probablity
the ratio of a number of equaly likely outcomes in an event to the total number of possible outcomes
transitive
If a=b and b=c then a=c
ten thousandth

thousandths
The third place value after a decimal point. Is the third largest decimal value. It takes 1,000 thousandths to make a whole.
