IF Functions - M L Humphrey - Bog

The IF functions are some of the most powerful functions in Excel.
A basic IF function lets you build a simple decision tree so that you have one outcome under one set of circumstances and another outcome if those circumstances aren't met. You can then nest IF functions to make a multi-level decision tree that covers as many different scenarios as you want. (Or close to it.)
Then there are the COUNTIFS, SUMIFS, and AVERAGEIFS functions that let you count, sum, or average a list of values, but only when your specified conditions are met.
