So in lab, I've measured the number of times it takes for a pendulum to swing in 60 seconds. I do this three trials for every change of length. Now, I want to take the average of these numbers, which is the value I get adding them all up and dividing by three. I get a decimal. How many sig. figs. should I keep? It doesn't make sense to keep even one decimal point, but I'm not sure.(adsbygoogle = window.adsbygoogle || []).push({});
