Give the definitions of:
Mean
Median
Mode
Range
Mean: The average of the data
Median: The middle point of the data
Mode: The most often number
Range: The distance from the highest to the lowest
The distance a number is from zero, always positive
Absolute Value
The equation that shows a relationship of proportionality.
y=kx
A number by itself
Constant
Complementary angles
The ranger from the middle half of the data set.
Interquartile
Any number written as a fraction
Rational Numbers
Proportional Relationship
The number multiplied by a variable
Coefficient
The sum of 2 angles is 180 degrees.
Supplementary Angles

What is the difference between Theoretical and Experimental Probability?
Theoretical probability is the reasoning of the probability.
Experimental probability is the actual data from experimenting.
A flipped version of a fraction
Reciprocal
A rate with 1 as it's denominator. Often uses "per".
Unit Rate
A mathematical sentence comparing expressions using greater and less than.
Inequality
Opposite angles from two intersecting lines are equal.
