Measurement Lab You will be graphing circumference (cm) vs. diameter (cm) for several different circular objects, and finding the slope of the line of best fit using the CapStone program. Write out or paraphrase the questions below before answering them. Pre-lab: 1.Given that we will be plotting circumference (cm) vs. diameter (cm), a.What variables will be on each axis? b.What units should the slope and y-intercept of the line have? EYA c.What is the meaning of the y-intercept in terms of this graph? EYA d.If a group found the slope of this graph to be 5 (note, that this might not be the actual relationship you’d expect), what would that mean? EYA
2.What do you already know about the relationship between the circumference of a circle and that circle’s diameter? Be as specific as possible in your answer, if you don’t know what the relationship should be, make sure you state that. Any specific relationship you know about the relationship between circumference and diameter or stating you don’t know.3.Write out a hypothesis (remember a hypothesis is an educated guess, not just any guess, so you must say why you think that it doesn’t have to be correct, it just needs to be rationally explained why you think that). a.What do you expect to find as a slope of the line of best fit for the circumference vs. diameter graph?
