Interests:

Teaching courses in statistical computation and interpretation,
mathematical and statistical problem solving with computer pro-
gramming languages; teaching computing basics and applications.

Special interests include measurement theory; the general linear model,
applications of matrix algebra, (heretical) perspectives on statistical
significance and hypothesis testing,and computer programming languages.

Demonstrable versus imaginary benefits of computing; unwholesome impacts
of computing and especially of the Internet and computers and the school
setting; the effective and irrelevant applications of Distance Learning.

Announcing!

Watch this space for course announcements and other relevant information. Summer 3 is the former Summer-II and it runs from July 12 to August 12.

Now  available:  See the links menu for  generic  SPSS codes  that run  in SPSS Windows
Production Facility  or   SPSS PC  Syntax Editor  modes.   Find  schematic  DATA  LIST,
CROSSTABS,  FREQUENCIES, DESCRIPTIVES,  CORRELATIONS,  FACTOR, RELIABILITY,  REGRESSION,
T-TEST,  ONEWAY, MANOVA, LOGISTIC REGRESSION, and more.   Especially important for true
multivariate sample comparisons and correlations problems using MANOVA (SPSS PC General
Linear Model  fails to  produce  required  output  for  these  approaches,  so beware!)

Make-up examinations for any course in the Department will be administered on Friday mornings between 8:00am
and noon.  Plan to finish by closing time, noon sharp.  The Department offices are on the  3rd floor of MCL.

My office is now MCL 302D. Other faculty offices are on the 3rd and 4th floors of MCL.

The most effective methods  for contacting me  remain email and dropping  in during office hours. Graduate students
enrolled  in my CSCI 5921 consultation for research design  and statistical analysis can  visit during office hours
in lieu of making fixed appointments, but do arrange appointments by email as desired. Undergrads drop in as needed.

Note in the links menu that I am building an on-line resource of course materials containing syllabus, reading notes,
worksheets  and other handouts.  It is under construction, and I will make many revisions from time to time.  Course
resource documents will be in formats that are Windows-friendly, such as Word, Notepad, Excel, and SPSS PC data sets.
