Introduction

Exam Three covers materials presented in the PowerPoint presentations and class lectures. It contains two sections. In the first section, students will be asked to answer ten multiple-choice questions worth 2 points each. In the second section students will be asked to answer two short-answer questions worth 10 points each.

There will be room on the back of the exam to write responses to the short-answer essay questions. You may bring ruled paper if you prefer. Blue Books are not necessary.

Dr. Sapp's Office Hours are MWF, 9:00 a.m. to 10:00 a.m., or by appointment. Students are invited to come to the office at any time and I will be happy to discuss the class materials with you.

These include: issues of measurement, specifying outcomes, measuring experimental contexts, specifying interventions, specifying the population, new vs. existing measures, and operationalization of success and failure.
