Explanation

Excel’s average function calculates the average of the values given. In this example, we use the range B2:B5 as argument. So it will take the average of the values in that range.

You can also use =AVERAGE(B2, B3, B4, B5) or even =AVERAGE(B2:B4, B5). Really any combination of numbers and/or ranges works.

Questions

How is the average calculated?

The average value is calculated by summing all the values and then dividing this sum by the number of values there are. So, for example, for the numbers 1, 2 and 3, the average is 1+2+3 / 3 = 2. So we summed all numbers (1+2+3) and then divided by 3 because there are 3 numbers in total.

What about the mode and the median? Are those available in Excel?

Yes, they are. You can use the MODE() or MEDIAN() functions to calculate those.

What happens with empty cells, text or errors? How does the average function deal with those?

The average function will simply ignore empty cells or text. Taking the average of errors will result in an error.
