One Variable Analysis Error
When I create a column of values in the spreadsheet view and choose one variable analysis and then click analyze, by default the statistics of the column are shown. If I next choose Z Estimate of a Mean in the drop down menu, all of the statistics carry over except the standard deviation which defaults to one even though it had been correctly calculated in the statistics view. There is a cell in which the correct value can be inserted, but why? It is a known value given the data that is selected. The bigger problem besides just seeing the incorrect value is that it is used in the error margin to give an incorrect Z Estimate of a Mean!
