Join Dennis Taylor for an in-depth discussion in this video Using the powerful AGGREGATE function to bypass errors and hidden data, part of Excel 2011 for the Mac: Mastering Formulas and Functions.
- Sometimes when you're working with data,…formulas give you a strange answer.…In this worksheet called Aggregate,…in columns A through D, we've got some data…based on employees, their sales in two different years,…and we're tabulating the change in column D.…We want to know the total amount of change,…that is so some of those are negative.…We'll simply put in an equal sum right here.…We could type that, or to make it slightly faster,…press command + shift + t.…We're about to tabulate the totals in column D.…I'll click the letter D in the column header,…and as I press return, of course,…we're getting something that's not desirable.…
Now, how big is that list?…Well, it's only 100 rows or so, in this case,…but it could be thousands.…Is that going to pop into view…if we start scrolling through here?…It might take us a while,…and there could be many errors.…We don't know exactly.…Let's say in this case we can track it down…because it's relatively short.…We've got a problem not only in column C,…also in column D, where we saw our formula problem.…
