jroese@lssu.edu WhatStat was designed to assist the user in the selection of an appropriate statistical analysis.  This is accomnplished via a series of questions regarding the focus of the analysis, the number of samples and variables involved, and how well the data conform to parametric assumptions. Responses to these questions will lead the user to one or more recommendations for analysis.  For most recommendations, a link to the relevant StatSheet is provided.  It is of course possible, in many cases, to apply these procedures to data sets for which they are not appropriate.  It is incumbent upon the user to understand the assumptions and limitations of any statistical analysis. WhatStat is not intended as an exhaustive compilation of statistical procedures.  WhatStat does, however,  provide the user with a broad spectrum of potential approaches to question pertaining to central tendency, distribution, variance, and correlation. StatSheets are Excel templates for completing various statistical analyses.  Each sheet provides a brief description of the analysis, instructions for its use, and any limitations regarding the number of samples or sample size that may apply. Computations for these analyses are drawn heavily from Biometry (Sokal & Rohlf, 1995), Introduction to Linear Regression Analyses  (Montgomery & Peck, 1982), Applied Nonparametric Statistics (Daniel, 1978), and Biostatistical Analyses (Zar, 1974). In most cases, all that is required is to enter data into the worksheet and review the results of the analysis.  It is, of course, the responsibility of the user to properly interpret these results in terms of the original hypotheses. StatSheets were created without macros to minimize security concerns.  I recommend that you save any downloaded StatSheets as  templates for future use.  If you wish to save a specific analysis you should re-name the file. (StatsSheets were created with Excel 2007 and may not work properly with earlier versions.)
