Averaging Data in Multiple Non-contiguous Ranges in Microsoft Excel
Excel is an incredibly powerful tool, capable of manipulating, analyzing, and presenting data in ways that can help drive business decisions. One common task you might come across is the need to average data across multiple non-contiguous ranges. This might sound tricky, but with the right approach, it's surprisingly straightforward. Let's break down how you can become a pro at this.
Quick Background: Averages in Excel
Before we dive into averaging across non-contiguous ranges, let's briefly touch on how to average in Excel. Excel's AVERAGE function calculates the average (arithmetic mean) of a range of cells. The syntax is quite simple: AVERAGE(number1, [number2], …). Each 'number' argument can be a list of values, cell references or ranges.
For instance, to average the numbers in cells A1 to A5, you'd use =AVERAGE(A1:A5).
Averaging Across Non-contiguous Ranges
But what if you want to average across multiple ranges that aren't right next to each other? Here's where things get interesting. You'll still use the AVERAGE function, but you'll need to include each range as a separate argument.
Here's an example. Say you want to average the numbers in cells A1 to A5 and C1 to C5. You'd use =AVERAGE(A1:A5, C1:C5). Easy, right?
Handling Errors and Non-Numeric Data
Things get a bit more complex when your ranges include non-numeric data or errors. If a cell contains text, Excel will simply ignore it when calculating the average. But if a cell contains an error, the AVERAGE function will return an error.
Fortunately, there's a solution. Excel's AGGREGATE function can average across ranges while ignoring errors. The syntax is AGGREGATE(function_num, options, ref1, [ref2], …). To use AGGREGATE to average across our previous example while ignoring errors, you'd use =AGGREGATE(1, 6, A1:A5, C1:C5).
