Question 1: Which measurement gives the BEST value for the mass of a single paper clip? (BEST value includes both accuracy and precision)
Claim: The measurement accepted as having the best value for the mass of a single paper clip was .411493 grams (Where best accounts for both accuracy and precision). This value was achieved by taking the average weight of a total of 30 paper clips, all of presumably varying weights.
Evidence/Reasoning: The “best” value that maintains precision and accuracy to the furthest extent would be the same aforementioned average weight of 30 paperclips, total. When 30 paper clips were weighed, they were a weight of 12.4258 grams; accuracy was achieved due to the inherent properties of having the most significant figures out of the multiple weights taken in the lab, which then results in the average possessing the most significant figures as well. Precision was also achieved, thanks to the inherent properties of averaging: The 30 total paper clips were essentially assigned their average collective weight, despite their own individuality.

The more significant figures provided in a value the more precise it is. And with the more paper clips provided, the even more precise the average of 1 paper clips mass will be due to the average involving more and more paper clips to account for. External variables are eliminated more and more with the higher volume of paper clips as well. For example when a single paper clip was weighed, let say that there was finger oil or some other substance on the paper clip. This would have given an inaccurate measurement. However when given 30 paper clips the extremities for inaccurate measurements are hidden or dwindled from the end value due to the higher volume of paper

    In measuring substances in the lab, reporting data, and performing calculations, it is both crucial important to be as precise and accurate as possible and also not to report false data. The rules of significant figures (digits in a measurement that reflect the measurement’s accuracy) allow us to have a methodical means of ensuring that the data and calculations we report reflect the accuracy that the equipment or data provide. To follow the guidelines for the correct number of significant figures, it is important to know the rules for multiplication and division, for addition and subtraction, for rounding, for measuring, and for scientific notation.…

    Yes, it matters. I should use the same balance for all of the five weighings so I know that my baseline data is the same for each weighing (the balances could be slightly off and skew my numbers). I could use the tare option in these weighings (i.e. subtract the weight of the empty graduated cylinder from the gross weight to determine the weight of the water). Using the tare weight would account for any discrepancies in the weight of different graduated cylinders.…

    Separation of powers is an act of vesting the legislative, executive, and judicial powers of government in separate bodies. (Losco and Baker 2013, pg 23) The United States is focused on this thought of discrete branches of government with distinct responsibilities. Power is divided in the U.S. government in two significant ways. Originally, power is distributed amongst the state and national government, and following, power is shared between the three branches of national government.…
