histograms are ok and handle frequencies, but I mean: I have data in which X is expressed as class interval (ex. classes of age), I need a method to input data to calculate statistics...
0-12 3
13-24 4
25-30 6
31-40 4
...
then make statistics on X and frequencies (or, in 2var stat, also on Y)...

thanks
