	download: Advanced Higher Uncertainty Using Linest Function (46.57KB) clicks: 390 added: 13/08/2010 clicks: 390
This document will explain how to use the Excel Linest function. The Linest function should be used to find the error in the gradient of a graph. This error should be considered the overall uncertainty for an experiment if the correct variables have been graphed. This should be used instead of the parallelogram method.
