How to include a formula as part of the criterion when using COUNTIF?

Question

I am looking to count how many values are higher than the average of the values listed.

	A
1	50
2	40
3	30
4	20
5	10

Total: 150
Average: 30

=COUNTIF(A1:A5,">30")
         Answer: 2

How could I replace the ">30" with a formula?

I tried the following with no success:

=COUNTIF(A1:A5,""">"&AVERAGE(A1:A5)&"""")

=COUNTIF(A1:A5,textjoin("",TRUE,""">",AVERAGE(A1:A5),"""")

Answer 1

This should do it:

=COUNTIF(A1:A5,">"&AVERAGE(A1:A5))

The & concatenates the AVERAGE formula with the operand (in this case, the greater-than symbol).
