Introduction to the Psychometric Analysis

The aim of this chapter is to describe the detailed process of exam evaluation, before and after implementing the exam. Exam evaluation starts by a qualitative review, which takes place before exam administration, and is followed by a quantitative analysis. The quantitative exam analysis is, in turn, classified into two parts: examinees' scores analysis and post-exam psychometric analysis. Qualitative and quantitative methods utilized throughout the exam evaluation process will be discussed. The chapter starts off by defining and differentiating between the three most popular theories behind the process of measurement, in this case assessment. Afterwards, the statistical methods used in exam evaluation are explained and elaborated using simple and descriptive examples. By the end of this chapter, the reader is expected to be able to: 1. Describe the qualitative evaluation of exams. 2. Define and interpret the basic statistics used in analyzing examinees' scores and psychometric analysis of MCQs. 3. Interpret the basic statistics used in the quantitative analysis of exams which includes examinees' scores analysis and post-hoc exam psychometric analysis.
