This guide has been designed as a quick reference for the use of Inferential Statistics to extrapolate information about your project from a sampling of data. Since we typically cannot gather 100% of the information we need to proceed with our project we must employ some tools that allow us to make acceptable conclusions with less than all the data. That is the benefit Inferential Statistics gives us – we are able to make reasonable conclusions from less than all the information. This is a 16 page reference guide including any applicable templates and data sets.
