To investigate length keep mass constant.
Period should be proportional to square root of length.
To investigate mass keep length constant.
Period should be independent of mass.
Find g from:
T = 2Pi x square root (length / g)
Use only very small amplitudes of oscillation as the algebraic relationship breaks down at larger amplitudes.
Time over (say) 20 oscillations and then find the average.

The time period of a simple pendulum is given by
T = 2xpixsqrt(l/g)
The variables l and g must be kept constant

Depends on the experiment. You keep anything constant that you're not studying.
