The second two graphs will show the average popped and unpopped kernels (one graph per brand). Due tomorrow.
2. Examine your data/observations/graphs. Write down anything that you noticed along the way. Write down any relationships between variables or brands that you notice (whether similarities or differences). All of this should be recorded in the appropriate section of your log. If you are unsure where it belongs, call a friend and find out. Start tonight, can finish tomorrow.
