For our first challenge, we were supposed to make a device that will launch a starburst a certain number of inches. We kept track of each launch here and our group did a take on the slingshot. We had limited materials, and, in my opinion, it was pretty bad. But afterwards, we took our data and turned it into a box-and-whisker plot. You will find our data on the doc.
I have no preview for this, since I can't figure out how. But we took a test to see if we understood between precision and accuracy. Precision is how many times your arrows hit the same area on the target. Accuracy is how close your arrows land to the bull's eye.
