Checking for normality in excel
http://brownmath.com/stat/nchkxl.htm WebDetermining whether data is multivariate normally distributed is usually done by looking at graphs. First, you determine whether the data for all the variables in a random vector are normally distributed using the techniques described in Testing for Normality and Symmetry (box plots, QQ plots, histograms, analysis of skewness/kurtosis, etc.).
