In the lab we measured graduated cylinders and we used a ruler to find specific measures of pennies and liquids. Significant figures depend on estimations and major/minor divisions. These numbers are important to tell specific measurements in your data like when we used a graduated cylinder( 25 mL) we wrote the amount of liquid was 20 mL, but when we looked back further we could've used another significant number as a decimal to be more precise. So our overall answer should've been 20.0 mL because when can use our eyes as judges to break down the divisions on the cylinder even further into .5 mL. Accuracy against precision is based on accuracy describes how correct your value that you measured is such as doing the math in the pre-lab question number three. We showed our worked and used a calculator to ensure that our answer was right. Precision is the close-ness of several measurements of the same amount as in data table B. Where we measured the same liquid over again to check the closeness of our measurements.
