1. Warm up
Smithers’ thinks that a special juice will increase the productivity of workers. He creates two groups of 50 workers each and assigns each group the same task (in this case, they're supposed to staple a set of papers). Group A is given the special juice to drink while they work. Group B is not given the special juice. After an hour, Smithers counts how many stacks of papers each group has made. Group A made 1,587 stacks, Group B made 2,113 stacks.

3. 5 Parts of a Graph

4. 1. Label Axis
The independent variable goes on the horizontal axis (x-axis)
The dependent variable on the vertical axis (y-axis).
Write a short descriptive label that represents each axis. The label is written vertically from the bottom up.

5. 2. Units of measurement:
Write the units in parenthesis after the axis label—often this is an abbreviation
For example: km, mm, ml, dm, dg

6. 3. Intervals:
Choose intervals that make it easy to read and so the data occupies the majority of the graph. You can include a break in the axis if there is a large gap between zero and the data points. Be careful not to exaggerate the variations in the data if you do this.
Is your graph easier to read in increments of 5’s, 10’s, 20’s…

7. 4th Data:
Plot the data points on the graph.

8. 5th Title:
Choose a title for the graph that uniquely identifies it. The title should not just repeat the labels, but add information specific to what the data represents.
