Based on your graph, did the amplitude affect the period of the pendulum (i.e. is there a trend)? If there is a trend, what is the trend? If there is not a trend, how did you determine that from the graph?

Explanation / Answer
Based on the graph it is clear that when amplitude is small there is negligible change in the time period of pendulum however as the amplitude go on increase the time period of pendulum is also increased.
