              inerSTAT-a     v1.3      March 1999
*****************************************************************

inerSTAT-a is a worksheet for MS Excel which allows you to easily
perform some basic statistics for up to 20 groups:
- Analysis of variance (ANOVA, 1-way and/or 2-factors)
- Simple Student's t-test (for non paired data)
- Tukey's test
- Dunnett's test

You only need to introduce number of values, mean, and standard
deviation or, if you prefer, standard error of the mean.

I developed this worksheet in MS Excel 97 (TM). However, this 
worksheet must also have good performance in Excel 4.0.

It is strongly recommended to extensively assess the performance
of this worksheet before rely on it. Neither I nor the Instituto
Nacional de Enfermedades Respiratorias assume any responsability
for potential errors on this worksheet.

This worksheet is FREEWARE, so you can freely distribute it your
colleagues, as long as it is not modified in any way.

I WILL DEEPLY APPRECIATE IF YOU SEND ME AN E-MAIL
IN ORDER TO KNOW YOUR OPINION ABOUT THIS WORKSHEET.

MY E-MAIL IS  mhvargas@mailer.main.conacyt.mx

I intend to develop in the future other worksheets for common
statistical or pharmacological procedures. Please, let me know
if you are interested in a particular procedure.
