Please note that all my software is constantly under development.  I do my best to verify the code and the algorithms; but unfortunately, I can test the software only so much by myself (or even with help from a few colleagues and students).  Please contact me if you find bugs or errors and I will do my best to fix them quickly.  I also welcome any suggestions you might have to improve the programs (or even new programming ideas).  Of course, this also means that if you find something you like, you should check back occasionally to see if there is a new upgrade available.

Most of the documents available with the programs (e.g., user guides, instructor guides, lesson plans, student exercises) are in Adobe Acrobat PDF format.

If you need the Adobe Reader, you can download it from their web site free using the following link:

BMA: Basic Matrix Algebra (for Statistics)

BMA is a Windows 9x/NT/2000/XP program written in Delphi Pascal that performs matrix manipulations.  It is designed for use in advanced statistics courses where a conceptual understanding of matrix algebra is desired without much calculation by hand.  It takes the user step-by-step through several matrix algebra functions, including addition, multiplication, transposition, and inversion. 

BMA was most recently presented at the annual meeting of the Mid-Western Educational Research Association, October 2003, Columbus, OH:

DGW: Data Generator for Windows

DGW is a Windows 9x/NT/2000/XP program written in Delphi Pascal that generates both Univariate and Multivariate data.  The program assists in the process by providing simple choices for several research scenarios (e.g., 3-group analysis, regression analysis). 

DGW was most recently presented at the annual meeting of the Mid-Western Educational Research Association, October 2003, Columbus, OH:

FISH: Friendly Introductory Statistics Help

FISH is a Windows 9x/NT/2000/XP program written in Delphi Pascal that performs introductory descriptive and correlation analyses.  It is intended to be used as a supplement to introductory statistics courses.  It is designed for use in basic statistics courses where a conceptual understanding of statistics is desired without much calculation by hand.  It takes the user step-by-step through the calculation of means, standard deviations, z-scores, and correlations.

FISH was most recently presented at the annual meeting of the Joint Statistical Meetings, August 2004, Toronto, Canada:

The poster presented for JSM should be published in 2005 in the Proceedings:

HMF : Harmonic Mean Finder

HMF is a NEW little Windows 9x/NT/2000/XP program written in Delphi Pascal that calculates the Harmonic Mean in a variety of ways (particularly useful for Power and Sample Size analyses).

MC2G: Monte Carlo Analyses for 1 or 2 Groups

MC2G is a Windows 9x/NT/2000/XP program written in Delphi Pascal that runs Monte Carlo simulations for several single sample and two-sample tests:  Independent t, Dependent t, Single-sample t, Mann-Whitney-Wilcoxon, Wilcoxon Signed Rank, Pearson Correlation, Spearman Rank-Order Correlation.  By providing the total number of rejections at the user-specified level of significance, MC2G performs robustness analyses when means are equal and power analyses when the means are not equal.  The original purpose of the program was to assist in the instruction of power analysis and violations of assumptions for introductory educational statistics courses.  However, with a little effort the program can be used to answer actual Monte Carlo research questions. 

MC2G was most recently presented at the annual meeting of the Mid-Western Educational Research Association, October 2003, Columbus, OH:

A program announcement and example lesson plans for MC2G was published in 2003 in Understanding Statistics:

MC3G: Monte Carlo Analyses for 3 Groups

MC3G is a Windows 9x/NT/2000/XP program written in Delphi Pascal that runs Monte Carlo simulations for 3-level ANOVA. By providing the total number of rejections at the user-specified level of significance, MC3G performs robustness analyses when means are equal and power analyses when the means are not equal.  The original purpose of the program was to assist in the instruction of power analysis and violations of assumptions for introductory educational statistics courses.  However, with a little effort the program can be used to answer actual Monte Carlo research questions. 

MC3G has essentially been replaced by MC4G (see below).

MC3G was most recently presented at the annual meeting of the American Educational Research Association, April 2002, New Orleans, LA:

MC4G: Monte Carlo Analyses for up to 4 Groups

MC4G is a Windows 9x/NT/2000/XP program written in Delphi Pascal that runs Monte Carlo simulations for up to 4-level ANOVA. By providing the total number of rejections at the user-specified level of significance, MC4G performs robustness analyses when means are equal and power analyses when the means are not equal.  Its initial purpose was to illustrate a variety of Type I Error problems associated with ANOVA (e.g., violations of assumptions, compared to multiple t tests, probability of at least one Type I Error from multiple orthogonal tests). 

MC4G was most recently presented at the annual meeting of the American Psychological Society, May 2004, Chicago, IL:

An article about MC4G is in press to be published in 2005 in Teaching of Psychology:

MCCM: Monte Carlo Correlation Matrices

MCCM is a Windows 9x/NT/2000/XP program written in Delphi Pascal that performs Monte Carlo analyses for several bivariate correlations simultaneously, particularly useful to show the effect on Type I error (or power) when testing several bivariate correlations all at alpha of .05.

MCMR: Monte Carlo for Multiple Regression

MCMR is a Windows 9x/NT/2000/XP/Vista program written in Delphi Pascal that performs Monte Carlo analyses for several multiple regression with up to 6 predictors.

MCMR was most recently presented at the annual meeting of the American Educational Research Association, March 2008, New York, NY:
