I am a statistical near-illiterate, trying to write an introduction to stats for real stats illiterates, using Excel data analysis functions. I have problems with some of the procedures and would be interested to know the algorithms used. Does anyone know whether these can be found or whether anything has been written on the use of Excel as a stats resource? The covariance and the two factor Anova especially appear a bit odd.
