Using AVERAGE With Other Data Types:

Average function in excel working with other data types

  • Dates: Excel treats dates as serial numbers, so averaging dates gives you a midpoint date
  • Currencies: Treated as numbers and included in the average.
  • Times: Times also work with the average function!
  • Percentages: Percentages can also be used effectively.
  • Text: Ignored by AVERAGE. You cannot use average for text.

Understanding how formulas work in detail, and what data types they can be used with is key to taking advantage of Excel.

Simple Example

Imagine you spent £200, £150, and £250 on groceries over the past three months.

To find your average spending, type these amounts into cells A2, A3, and A4.

In cell C2, enter the formula

=AVERAGE(A2:A4)

The result in A4 will show your average grocery spending!

Advanced Example

Let’s say you have a list of weekly sales figures for the quarter and want to find the average sales for weeks with sales over £500 to focus on high-performing weeks.

Your sales data is in cells B1 through B12. In cell C1, enter the formula

=AVERAGEIF(A2:A8, ">500")

This formula will calculate the average sales for all weeks where the sales figure is greater than £500, giving you insight into your best sales weeks!
