st: Quick display of categorical data
Hi. I have what ought to be a common problem: I'm beginning to analyze
some survey data, and much of the data consists of responses to
questions on a 1-5 scale, a few responses on a 1-3 scale, and a few
responses to limited nominal scales. I have too many cases (1,000+) to
learn anything from a stemplot (although I suppose I could sample 1/10
of the cases for this purpose), which isn't meant for categorical data
anyway, and it's way, way too cumbersome to individually create and
print bar charts using Stata graphics (unless there's something I don't
know about how to do this, which is likely). Ideally, what I'd like is a
display something like this:
Some inter |
esting var |
iable | Freq. Percent Cum.
------------+-----------------------------------
Never, ever | 315 30.79 30.79 30 X X
Maybe once | 204 19.94 50.73 X X
Occasionlly | 149 14.57 65.30 20 X X X
Pretty oftn | 55 5.38 70.67 X X X X
Always! | 300 29.33 100.00 10 X X X X
------------+----------------------------------- X X X X X
Total | 1,023 100.00 1 2 3 4 5
I would happily settle for just the ASCII bar chart, and a horizontal
bar would be fine. The point is to be able to get a sense of the data at
a glance, without wasting a bunch of paper. Does anything exist along
these lines? Am I overlooking something really obvious? My search didn't
reveal anything ... Thanks in advance.
