About this lesson
Counting things: COUNT, COUNTA, COUNTBLANK
=COUNT(C2:C16) counts cells holding numbers, =COUNTA(C2:C16) counts every cell that isn't empty (text included) and =COUNTBLANK(C2:C16) counts the empty ones. So COUNTA − COUNT is the number of text entries.
=COUNTA(A2:A16)What you'll practise
Track debtor confirmations on a Big 4 audit: how many went out, how many came back with an amount, how many are still unanswered, and the response rate.
