Combine 4 Columns into 1 Table For PivotTable Report (without Power Query)
See how to take 4 columns with Survey results for error rates (Yes/No) for the years 2011, 2012, 2013 and 2014 and combine them into 1 table so that we can create our PivotTable Report. Also see a Chi Square Test to test whether 4 population proportion error rates are significantly different.
