For MGMT 302 - Business Policy & Strategy, students are assessed each week using a bank of multiple choice questions. These questions are delivered to students in-class using Cecil.
Having written over 600 questions there is, nevertheless, the lingering question, "Do they work?".
This is where I have adopted TestGraf to carry out statistical analysis of the questions. This analysis allows me to diagnose problems with whole tests, individual questions, and items with a question. Consequently, I have strong evidence of the quality, in terms of discrimination and validity, of questionnaires I have written.
My use of TestGraf has been so successful, that Cecil have incorporated TestGraf's main functionality into Cecil's test engine.
