function in Microsoft excel we were able to calculate our standard deviation which was 2.22. With the expected value being two this was a good result because it is very similar.

Basically, there should be a noticeable and systematic increase in the standard deviation based on an increase in size of the target circle, while the matching circle mean should stay close to the actual physical size of the target circle. In other words, it should be possible to see a progressive and regular increase in the standard deviation from a 10-, to a 30-, to a 50-pixel circle; and alternately, a systematic decrease in the standard deviation when moving in the opposite direction from…
