Graphs

• This presentation will focus on the different steps in takes to make a good graph

Step 1: Draw your Axes

• Plural of Axis - Axes
• Y axis - Vertical
• X axis - Horizontal
• 
• Legenda: Axes featuring Y, X, -Y, and -X

Step 2: Label your axes and title the graph

• Always label with units that are CONSISTENT
• X = independent variable
• Y = dependent variable
• Title should go as follows: DV vs. IV
• Remember:
• D - Dependent
• R - Responding
• Y - Y axis
• M - Manipulated
• I - Independent
• X - X axis
• 
• Legenda: A correctly labeled graph

Step 3: Identify the range for your X & Y

• How to identify range:
• Look at the highest and lowest point from each variable ------>
• X - 4&10 Y- 16&98
• Subtract lowest from highest
• 10-4 and 98-16
• Then you get your range!
• X- 6 and Y- 82
• 

Step 4: Identify units for your variables

• Take your range and divide it by the number of lines on your axes.
• Ex - Say your range is 20 but you only have 10 lines, you would do 20/10 and get 2
• 2 would be your unit of increasement
• Say you get a decimal - for example 1.6666- you would round UP to 2.
• Always round up
• Repeat for all axes

Step 5: Plotting Data

• Start with first point of data
• |
• -----------> Ex) Time: 1 Distance: 15
• Plot data where two lines meet
