Abstract
In this paper, several Educational Statistical Tools for summarizing a test marks are discussed. The mean, variance, 5number summary, Difficulty index and Discrimination index are discussed in details. The tools are simple, so that they can be understood by almost all instructors regardless of their backgrounds in statistics. The contents of the paper can be very useful for users of statistics at different areas and in particular, teachers.
