Find G in Pendulum Experiment: Help Solve I Need

[cpriyan]

I Need help...I'm not getting the value of "g" correctly..please someone help/
This is a pendulum experiment to find "g".

S L EL T TT T^2 G


1 80 82.43 35 35/80?? (35/80)^2?
2 70 72.43 33 33/70?? (33/70)^2?
3 60 62.43 31 31/60?? same


Plz help me find the value of g , time period and t^2...i'm getting confused...or missing out something...nd not getting the reqd result...when i apply T^2 = 4(pi)^2/g formula/...PLZ HELP!

EL =Effctive Length
TT =Time Period

What are all your variables/values and what exactly are you trying to solve?
It looks like you have three trials with different values for everything but it isn't presented in a manner that makes sense without some more explanation.

S is sample? L is length? T is time?
