Yes, you can average percentages. Just type =AVERAGE( and select the cells with percentages. Excel handles it like a champ. Just make sure the result cell is also formatted as a percentage. Otherwise, you’ll get a weird decimal like 0.15, which is technically correct but looks like a typo.
You can also average times. Imagine you’re tracking how long it takes to make toast in the morning. Just use the same formula, and Excel will give you the average time. It’ll be somewhere between “burnt” and “still cold.” Life is a journey, and Excel averages those journeys too.
