You might also want to try the frequency function as a array formula.
{=FREQUENCY(Data,Counts)}
You need to have a column with the "bins" you want to find the frequency of (1,2,3 etc)
Also, with array formulas, you have to select all of the cells at once. ie: if you're going to put your frequency counts in cells A1:A10, you select the entire range, enter the formula in the bar at the top, and then press ctrl+shift+enter.
