What is Statistical Data Analysis

Assessment is an important phase of the teaching and learning processes. Assessment generates a big amount of data, which in the case of summative assessment is in the form of students' grades. In e-assessment application, these grades are easily collected and stored. The analysis of the grades is very important to directly evaluate e-assessment and thus indirectly evaluate the teaching and learning processes. This chapter presents a practical example of analysis of grades obtained during an e-assessment process implementation using statistical methods. Important tips on how to correctly use these statistical methods are presented throughout the chapter. The analysis concerns seven years, and a positive evolution of the grades is verified.
