Introduction - The purpose of the lab is to familiarize students with scientific methods to measuring and analyzing data based off of uncertainties. Uncertainty is half the smallest measure. Propagation of Uncertainty is the effect of variables uncertainties on the uncertainties of a function based off them. , where p and q=1).
