How to calculate frequency of value?

Hey,

really basic question. I have a long list of values ranging from 1 to 4, each representing a different thing. How do I calculate the frequency of, say, 3 in that row? I can't get it right. :/

Thanks

Why not just use countif if all you are trying to do is see how many time "3" occurs in your list.

=COUNTIF(A1:A100,3)

or for row 1

=COUNTIF(1:1,3)
