Rules of XY-Coordinate Graph
• Ordered pair is written as (x, y)
• First number of the ordered pair is called the x- coordinate (the horizontal axis)
• Second number of the ordered pair is the y- coordinate (the vertical axis)
• Origin is represented as (0, 0)

A Complete Graph
• All graphs should be neat, easy to read and be constructed with a straight edge
• Units along the axes are clearly labled
• The axes are labeled with words
• Must have a title
• Must have equal intervals
• Needs a key or a legend

Stem and Leaf Plot
• The stem is the part that represents the leading digit of the number
• The leaf represents the other digits after the leading digit

3 1,1,2,3,3,5,7,9
4 1,2,5,7,8,9
5 1,8,9
6 1,2,8,9

Box and Whisker Plot
• Box and Whisker Plots are divided into quartiles
• The lower half of the set of numbers is the lower quartile
• The upper half of the set of numbers is called the upper quartile
• To find the quartiles the numbers have to be arranged from least to greatest

Line Plot
• A line plot is used to show amounts or choices easily.
