1. Suppose you measure the circumference of a circle and its diameter, then divide the circumference by the diameter. The result ought to be it. If your result is 3.15 did you just prove that it is 3.15? 2. Suppose you want to find the length of a rod. Do you think that decreasing the number of times you take a measurement of its length would improve the precision of your result? 3. You take thirty measurements in order to find the length of a rod, you calculate the average and obtain the value LO. Supposed that now a different person takes twenty measurements as well of the same rod, then calculates the average and obtains the same LO as you. Does it mean that both of you obtain a result with the same precision and accuracy? **all of these are yes or no questions* *** 1.
