Graphing AIM: to show the relationship between dependent and independent variables

What are the Characteristics of a Good Graph? Think, Pair, Share! 1. Title 2. Labeled Axis 3. Proper scaling 4. Using the whole graph 5. Including units!

Parts of a Graph Label the X and Y axis, include units Title – X verses Y is the best title Label the X and Y axis, include units Include a consistent scale for each axis

Acceptable scales: 0, .1, .2, .3, .4, .5, .6, .7, .8, .9, 1.0.. 0,1,2,3,4,5,6,7,8,9,10… 0, 2, 4, 6, 8, 10, 12, 14 … 0, 5, 10, 15, 20, 25, 30, 35…

Variables X axis is always your Independent Variable Y axis is always your Dependent Variable If we wanted to test the affects of light on plant growth what would be the independent variable?

Plot points carefully and accurately. Be sure to connect the points with a line. Label lines and/or provide a key

Bar Graphs Used to compare things

Line Graph shows the relationship between two variables Dependent Variable 2 4 6 8 10 12 14 16 Independent Variable
