Hi all,

I have a dataset that consists of students (studid) in 49 schools
(schid) responding to a survey. They were asked their impressions of the
curriculum ("do you believe time devoted to subject xxx was ....") and
all responses were categorical (with 1 denoting 'not enough', 2 denoting
'just right', and 3 being 'too much'). A slice of the data is:

list    schid studid timepub08 timefin08 in 30/40

   +--------------------------------------+
   schid   studid   timep~08   timef~08
   --------------------------------------
30.    2     6910          2          2
31.    2     6911          2          2
32.    2     6912          2          3
33.    2     6913          3          3
34.    4     7299          2          2
   --------------------------------------
35.    4     7300          2          2
36.    4     7301          3          1
37.    4     7302          2          2
38.    4     7303          2          2
39.    4     7304          2          1
   --------------------------------------
40.    4     7305          1          .
   +--------------------------------------+

Question: Is there a way to generate a (or collapse this) dataset to get
school levels variables? I am interested in school level variables that
captures the number of responses to each category (1 'not enough' 2
'just right' and 3 'too much') for each question (timepub08 timefin08).

Many thanks for the advice.
