Homework Statement

Hi, i have to calculate acceleration of gravity using chi-square.

I have some measures of g, but I don't know how i can calculate g using chi-square.

2. The attempt at a solution
I haven't any idea to deal with. Can you suggest me some ways to solve the problem?
Thanks a lot

Chi-squared is a method of matching a prediction/theory to data.
If you have a set of values, and you want to find the 'best fit' (i.e. the best average value), you can use chi-squared.

More specifically, chi-squared is a measure of how good a fit is. To 'use' chi-squared to fit data, one must generally apply an iterative numerical approach.
