                                                                                  Introduction


                     A branch of mathematics that uses probability is called statistics. Statistics is
                     the branch of mathematics that uses observations and measurements called
                     data to analyze, summarize, make inferences, and draw conclusions based on
                     the data gathered. This chapter will explain some basic concepts of statistics
                     such as measures of average and measures of variation. Finally, the
                     relationship between probability and normal distribution will be explained
                     in the last two sections.
