How to Create Average in Excelのやり方について詳しく紹介します。初心者でも安心のガイドをチェックしてください。

If typing =AVERAGE( feels like too much effort (we’ve all been there), Excel has a cheat button. Look for the AutoSum button on the Home tab—it looks like a Greek letter “E” (∑). Click the little dropdown arrow next to it, and select Average.

Excel will guess which numbers you want to average. Most of the time, it’s right. If it highlights the wrong cells, just drag and select the correct ones, then press Enter. It’s like having a mind-reading assistant who occasionally misreads your mind, but forgives you for correcting it.

Finding the Average Value With Excel's AVERAGE Function

This method is perfect for when you’re in a rush and your coffee hasn’t kicked in yet. One click, and you’re done. You can practically hear Excel whispering, “You’re welcome.”

What If My Cells Are Empty or Have Text?

Great question! Excel is smart about this. It ignores empty cells and text when calculating the average. So if you have a row of numbers and one cell says “Oops” or is blank, Excel won’t count it. It just averages the numbers that actually matter.

However, if you have a zero in a cell (a real number 0), Excel will include it. This is important if you’re grading papers and a student actually got a zero. But if they just didn’t show up, leave it blank, and Excel will treat them like they don’t exist—a little harsh, but mathematically fair.
