ABSTRACT
Statistics can be denoted in words or in symbols. Statistical notation that refers to the population uses Greek symbols. Statistical notation that refers to the sample uses upper- and lowercase letters. Most statistical concepts really are fairly easy to learn because concepts can be simply stated, concepts can be related to real-life examples, many of the same concepts run through much of statistics, and therefore many concepts can be related. A quite interesting statistical personality is William Sealy Gossett, who was employed by the Guinness Brewery in Ireland. The field of statistics is generally divided into two types of statistics: descriptive Statistics and inferential Statistics. The statistics of a nominal scale variable are quite simple as they can only be based on the frequencies that occur within each of the categories. The chapter also presents an overview of the key concepts discussed in this book.
