Can someone explain to me what exactly an array formula is?

=ROUND(AVERAGE(IF(F5:F10000,F5:F1000)),2)

still array-entered.

that worked great!!!
The formula reads like this: =AVERAGE(IF(F5:F10000,F5:F1000))

How would I go about rounding it two decimal places?

Try something like this:

=AVERAGE(IF(F5:F10000,F5:F1000))
this is an array formula so enter using Ctrl+Shift+Enter

how do I Calculate the average of numbers not in a contiguous row

(The column starts at F5 but I will continuosly add to the f
column,
so it
doesn't have an ending column.)

It's a simple worksheet calculating my MPG on my car, so I will

to it.
