The problem has to do with sig figs going down to 1. I've checked them multiple times by hand and with sigfig calculators but it is all the same. With 1 sig fig my standard deviation ends up being 0 which I am not sure that is acceptable.
It makes sense as the points are super consistent for measuring G but when it comes to filling out the tables having 0 for most parts bothers me.
The Attempt at a Solution
I have an excel document with all my data and calculations
