Variable: Length of string

Hypothesis: The longer the string, the faster the movement of the pendulum, hence the frequency increases, resulting in a shorter period for the pendulum to make a complete oscillation.

Line 1: As the length increases, the time increases.

Line 2: As the length decreases, the time increases.

Line 3: The time increases even though the length did not increase. This is not possible since the length has to change before the time can change as the time is dependent on the value of the length.

Line 4: The time did not increase even though the length increased.
