1. Your lab group takes 10 measurements of the period of a simple pendulum. They use small starting angles (roughly less than 25), but do not carefully measure the angle for any of the trials. What do you expect to see in your group's data? For example, how precise will the data be? Will the data agree with the theoretical period as predicted by the equation?

2. Based on the measurements of period at different masses, do you think that the period of a pendulum depends on mass? Defend your conclusion using any of the data analysis tools you have learned so far (e.g. visual comparison, T-scores, etc.). If you use T-scores, explain which points you tested and why. If you don't use a T-score, explain why it was not necessary.
