This week we took the plastic pieces out of the PIA plates and washed, sanitized, dried, then got our last set of measurements. Afterward, the average mass was calculated and added to the graph for comparison. We were kind of happy to see more results, but on Wednesday we were surprised to find significant differences in the margin of error. I was able to get some insight from John and, well.. I think next time I'll be sure to take a look at all possibilities (from a stats perspective) in gathering data. And it's not that we chose a bad way to collect data, but there are better ways and its good to really look into other possibilities while building your foundation. For now, there's not much to do about it but trudge through it.
