This book is about the number-crunching side of Excel. Formulas are the keystone to analyzing data — that is, digging out nuggets of important information. What is the average sale? How many times did we do better than average? How many days are left on the project? How much progress have we made? That sort of thing.
Formulas calculate answers, straight and to the point. But that’s not all. Excel has dozens of built-in functions that calculate everything from a simple average to a useful analysis of your investments to complex inferential statistics. But you don’t have to know it all or use it all; just use the parts that are relevant to your work.
This book discusses over 150 of these functions. But rather than just show their syntax and list them alphabetically, we have assembled them by category and provided real examples of how to use them alone, and in formulas, along with step-by-step instructions and illustrations of the results.
