Hypothetical Procrastination Experiment
• Question: Do you procrastinate before a project?
– Monitor Progress
– Present your data
– Dependent variable- “Y” axis
• Variable being tested
– Independent Variable- “X” axis
• Variable that affects the dependent variable
• Days before project is due and work completed
This is why we use graphs…
• Today I decided to monitor the progress of my projects over the time span in days. This will be compared to the percent completion starting from the first day I am assigned the project. One day one I was very studious and completed 25% of my project. Then I found out the packers lost and became depressed for the next two days but completed 25% more of my project before I found out. Then my mother-in-law showed and proceeded to lecture me which in turn depressed me for the next two days. I got nothing done. Then I realized my project was due and stayed up till one in the morning to finish the project. I was late to class.
Getting better…

Metric Review
• Mr. Hoeldtke wanted to burn his ditches with napalm . Because napalm is cool…duh! Unfortunately, Mr. H. didn’t compensate for the fact that his napalm distributer (Flamethrower) held napalm in liters and not gallons like he thought. For this reason Mr. H lives in a cardboard box on his ashy property. Don’t live in a cardboard box! Learn to convert!
Conversion review
• Your ditch can withstand the intensity of 40 liters of flaming fury. The napalm distributer only measures its cargo in gallons…how many gallons are in 40L of burning beautifulness?
Google Glory!
