Statistician is a comprehensive yet simple to use add-in for Microsoft Excel 2007 or later. The software performs high quality statistical analysis based on series of easy to use forms, activated via the Excel ribbon. Statistician works in a unique way when compared to other Excel based statistical analysis software. Most importantly, it allows the user to store a data set and perform multiple analyses on it, a method used by all high end statistical software, but lacking in many other Excel add-ins which require the user to reselect data over and over again when they return to the spreadsheet. Many customers, having used alternative statistical data analysis products in the past, are amazed by not only how powerful and reliable Statistician is, but how quick and easy it is to use.
