Basic math formulas
The basic math formulas in Excel allow you to do, well, basic math. The standard Sum, Count, and Average formulas are more or less self-explanatory and always useful. A few other formulas that are highly practical for all sorts of analyses are Percentile and Percent rank. These allow you to determine where a number lies on the distribution of a set of numbers. For example, if you have a set of interview scores and want to determine the top 90% cutoff score, you’d use these formulas to find the point of cutoff. Lastly, Rand and Randbetween are great for randomly selecting items within your data (ie, If you were running a contest and randomly needed to select a winner).
