Standard Deviation Experiment

The purpose of the experiment was to figure out which means of measurement was more accurate in reaching the proposed weight, the graduated cylinder or the pipette. Two new terms that were mentioned and crucial to the project were standard deviation and reproducibility. Standard deviation was a new term for me in the case that I had never used it in science before only in math classes, I did not understand why the difference between the data collected and the mean was important but now I see it is to see how different the tests were from one another and if the measurement is accurate in the sense that it is constant. The reason that reproducibility was different was because I was stuck on the fact that the experiment had to be repeated by us, and not asking the question , if others did the same thing as us would they be able to get similar data, it was an important reminder, ( Kinnes and Eddington).
My hypothesis was that the pipette was going to take a more accurate measurement because it was thinner and there was less of a

The data gathered from the first five trials using the pipette was a constant 9.9 grams until the last trial was 10.1 and the standard was 0.0894 which is far less the differences found in the next five trials using the graduated cylinder which weight in grams varied from .1 to .2 grams constantly and had standard deviation of 0.114. In the first five trials using the pipette the trend was that it was constant for the first four trials by being off of 10mL by by point one grams at 9.9 until the fifth trial where it was off by .1 mL at 10.1 this trial remained constant for the most part but for the graduated cylinder the numbers were to varied which showed its lack of
