Subject: CombiStat 1.1
CombiStat is a programme that performs two useful mathematical procedures
involving standard errors of the mean (SEM). Its main use is for combining
several Mean +/- SEM values into an overall Mean +/- SEM. This is a frequent
requirement for researchers repeating an experiment several times, each time
obtaining a Mean +/- SEM for the parameter(s) under study. Additionally, in
version 1.1 the programme will calculate the SEM and standard deviation of
both the ratio (X1/X2) and the product (X1*X2) of two independent variables,
X1 and X2, each having an associated SEM. For more information see the
accompanying Read me file.
CombiStat should run on any Mac and has been tested with System 7.6.1 and 7.5.3
The programme is freeware.
