>Hello,

I was hoping for some advice on how I might compare a sample with a
total population by a number of categories. The sample consists of
all persons who went before a special court over a 20 yearperiod.
There were three court outcomes, I'll call them A, B and C. Persons
could be charged with one of 10 types of offences.

I want to (1)  determine whether the offending of groups A, B and
C  were similar to persons who did not go to the special court
(e.g  are there any category of offences that is over-represented in
special court hearings).  I had considered performing 10 chi-square
but wondered if there was a more efficient or better way of doing
this and (2)  to adjust offending numbers for overall population
change (to determine if increases in the number of people going to
the special court is proportional to overall population increases in
the general community, of persons who have not committed offences).

Any assistance is much appreciated,

regards

Bob
