Kevin Boles Section 5 September 8, 2010 Normal Distribution Abstract: The object of today’s lab is to familiarize the students with significant figures and the role they play in determining normal distribution. It will help us become more familiar with calculating, collecting, and recording data both on paper and in graph format. This lab is designed to make students feel more comfortable when using laboratory equipment to complete laboratory tasks. In order to do this experiment, a stopwatch and pendulum are needed. Theory: The significant figures are important in physics because they describe how accurate any particular measurement is. When adding or subtracting two quantities it is possible to have an outcome with a different amount of significant figures than the two original quantities had. When multiplying or dividing quantities, the outcome should have the same amount of significant figures as the original quantity with the least amount of significant figures, which essentially means the least level of accuracy. In most cases, one measurement is not enough to
