The work presented in this report is my own, and the data was obtained by my lab partner and me during the lab period. Results and Calculations In this experiment, ten pieces of paper were weighed in order to obtain each paper’s mass. The purpose of this experiment is to become familiar with the use of Microsoft Excel. Below is a table of the entire test subject’s data.
