Question

The period T of a pendulum can be determined by measuring the time t for 20 complete
oscillations and then calculating the period. Some students are asked to explain the reason
for this method being more accurate than measuring the time taken for a single oscillation.
Tick the box next to the sentence that gives the best explanation.
The method eliminates errors from the measurements.
The method is more accurate because the experiment is repeated.
The method includes more readings so there is less chance for errors.
The method reduces the effect of errors when starting and stopping the stopwatch.
