Range
Distance between highest and lowest scores in a set of data.
The purpose of Venn Diagrams
compare data, likelihood of events
The purpose of Bar graphs
compare data overtime
The purpose of Pictographs
use visuals to compare data
The purpose of a table
organize a list of data
Purpose of a line graph
show change over time
The purpose of a stem-leaf plot
organize data that is somewhat close
The purpose of a histogram
range or frequency where most data falls.
The purpose of a frequency table
how frequently data occurs

How does changes to dimension affect area and volume?
area increase by x squared
volume increases by x cubed
Sphere volume
V = 4/3πr³
Cylinder volume
V=πr²
Surface Area of a sphere
SA=4πr²
Surface area cylinder
SA=2πr²+2πdh
Circle circumference
C=2πr
Area of a circle
A=πr²
Trapezoid area
A=1/2h(b1+b2)h
Rectable area
area= width x length
Reflection over x-axis
(x,y) -> (x,-y)
Rotation over the x axis
(x,y) changes to (-x,-y)
Translation over the x-axis

Equilateral triangle
all congruent sides
Isosceles Triangle
a triangle with at least two congruent sides
Scalene Triangle
a triangle with no congruent sides
