More on Sums
My post from last week, on using the Aggregate function to find the maximum and minimum of a range ignoring errors, was linked in the Contextures Blog’s weekly roundup, which also linked to the Contextures page of Sum Function examples. This includes sub-totals, grand-totals, Offsets, Sumifs, Sumproducts, and much more. It’s a comprehensive list, including clear examples and videos, and well worth a visit.

Someone comments that John Martyn comes to mind, so maybe this duo is not so surprising:
Max, Min, and Aggregate
Recently I needed to find the maximum and minimum of a range of values including some #N/A values. Searching found a variety of solutions, of which the simplest (that works in all versions) seems to be:
- =MAX(IF(ISNUMBER(datarange),datarange))
- =MIN(IF(ISNUMBER(datarange),datarange))
The function must be entered as an array function, i.e. type the function, then press Ctrl-Shift-Enter, rather than just Enter. The screenshot below shows a simple example:
The search also found the Aggregate function, which is new in Excel 2010, and provides a number of options for ignoring sub-totals as well as errors. The Aggregate function will return a number of different statistical functions, as well as Max and Min. These are documented with a tool=tip as the function is entered, as shown in the screen-shot below:
