I'm not sure if that is how you would calculate the uncertainty

1. The oscillation period of a pendulum is the time it takes the pendulum to move through one complete back-and-forth cycle. Suppose you use a stopwatch to measure this period 6 different times, getting the results 1. 10 s, 1.05 s, 1/13 s, 1.01 s, 1.08 s, and 1.02 s. On the basis of these measurements, what would you say the period of the pendulum is? Give a most likely value and an uncertainty. Total time : 6.39 5 uncertainty : 0.001 6 =.000 16 T = time Cycles = 6.39 6 - = 1.0653
