Getting Accurate Data


June 22, 2016

Today, due to the lost data we started our data collection over and began running tests at 5 minute intervals for the control group. After setting up the microscope yesterday, we were finally able to pinpoint exactly where to put the stylus so that we can go over the wear scar every time. Prior to this, our data indicated that the stylus went over the wear scar only some of the time. Hopefully this step will increase the accuracy of our data so that we could compare it to the profilometer. The microscope set up is shown in the photo.
