QUANTITATIVE TOMORROW please help!

I have the physics quant tomorrow on shm and oscillations etc.
We did a practice experiment with a pendulum and got told to time 5 oscillations then divide to find time period, T.
How many sig fig do I then leave T to because does it count as a calculation!
If so we got told to leave it to the same dp that the raw data was sf.
but then if t was to 2 dp eg 10.42s then I would have to leave T to 4 dp??!
please help urgently!

You measure and record data to the smallest increment the measuring device measures with an uncertainty of + or - one of those. For example 10.42 seconds would be measured to as many d.p as you have (2) and the uncertainty would be + or - 1*10^-3 seconds.
