logical test for each and every cell in range

i need to check to see if a given range of cells each fall within a range.
Say I had a column of data like this:

2
3
6
3
4

I want a statement that checks to see if each cell is greater than or equal
to 1, say. Is there a way I can do this without writing a separate IF
statement for each cell and another IF statement for those results?
