It's hard to get the slope of some of the graphs, but I used one and got around 18 m/s^2, which is not ridiculously far off from my answer. However, shouldn't the answer be 9.8 m/s^2? That is the gravitational acceleration constant, right?

It's fairly similar, but definitely linear, unlike most of those slightly curved graphs. I've tried adjusting it, but there is no way of linearizing it, as everything I've done results in a smaller r and r^2 value.

Length | Period 15.5 | 1.03 28.2 | 1.17 41.0 | 1.38 50.0 | 1.54 57.0 | 1.67 67.5 | 1.75 79.1 | 1.89 94.7 | 2.07 Length is in cm and period is in seconds. (These are also averages of eight different trials for each length)...

Sure, my slope was .0135 s/cm or 1.35 s/m. I then plugged in 1.35 for T and 1 for l (this may be the completely wrong way of approaching this, but I thought it made sense). So my equation looked like this: 1.35s = 2∏√(1m/g) and as I'm typing this I realized what I did wrong haha so...

I am doing a lab report for IB Physics SL and I am supposed to use the slope of the period of a pendulum graphed against the length to find gravitational acceleration. I am trying to use the equation T=2∏√(l/g) but I'm not getting the right answer when I solve for g. (the answer is in s^2/m...
