Student T-Test.. How to?


We have data with students Pre Course testing results and students POST Course testing results

We wish to determine if there is a statistical significance in knowledge increase.

A method to determine this is to use Student’s t-test

There exists in EXCEL a T-Test as part of the Analysis Toolpack

What is the best method to develop a T-test engine in Dundas -?
The RAW data contains 3 columns:
Student ID - Test results BEFORE - Test results AFTER

Cheers & Thanx.
