If you have made your way through the first 10 chapters of this text, then you may already have found that more and more people, strangers as well as friends, are seeking you out for your newly acquired expertise. (Not as many as if you were stunningly attractive or a film star, but a great many people nonetheless.) Your boss may even have announced that from now on you will be the official statistician of your group.
To prepare you for your new role in life, you will be asked in this chapter to work your way through a wide variety of problems that you may well encounter in practice. A final section will provide you with some over-all guidelines. You’ll soon learn that deciding which statistic to use is only one of many decisions that need be made.
