Abstract - This document outlines the format of the lab report and describes the Excel assignment. The abstract should be a short paragraph that very briefly includes the experiment objective, method, result and conclusion. After skimming the abstract, the reader should be able to decide whether they want to keep reading your work. Both the format of the report and the error analysis are to be followed. Note that abstract is not just the introduction and conclusion combined, but rather the whole experiment in short including the results.
