Sometimes, you may be asked to determine how many values exist in a list, including text. This is where COUNTA comes into play.
While COUNT only determines how many numbers are in a given range, COUNTA determines how many values (including text) are in a given range.

...if we wanted to figure out how many total friends were at the party, we could accomplish that with a COUNTA function like so!
We now know there are 18 friends at the Super Bowl party!
