inerSTAT-a - Version 1.3 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 test - Dunnett 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 or 5.0. This worksheet is FREE, and can be freely distributed as long as it is not modify in any way. This 1.3 version gains precision in the tests, and adds a 2-factors ANOVA procedure.
