Hi all,

I was wondering how to show frequency of a continuous variable in 
several ranges. For example, the variable "wage"measured with dollars 
and cents. In my data set, there are lots of values for this variables 
since people's wages are usually different from others. The command  
"tabulate" shows exactly frequency of each value. That's not what I 
want. I'd like to see the following information:

 range of wages        frequency    
    <=0.00                ??
  (0.00, 10.00]         ??
  (10.01,20.00]        ??
  (20.01,30.00]        ??
.....................

I know I could find number of observations in each range by using sum 
if wage <=0.00
sum if wage >0.00 & wage <=10.00
etc.

But I'm thinking maybe there's simple way to do this. Any suggestions?

Thanks!

Mandy Jia
