COSC100E Assignment #3                      Due Wednesday 11/20/85



Using the data collected in the interest survey, stored as:

		DRA0:[ATUCKER]INTEREST.DAT

and the data collected in the GRO opinion survey, stored as:

                DRA0:[ATUCKER]COSC100D.DAT  

write SAS procedures that will accomplish the following:
	
1.  Merge the data in the two data sets into a single data set,
and produce a listing of all variables in the result.  Each person
who appears in both data sets should have a single observation in
the merged result.  Persons who appear in one but not the other
will have missing values showing for some variables in the result.

2.  Group the responses to questions 6-14 in the interest inventory
by creating new variables MATH, ARTS, and JOCK, and giving
them values as follows:
    a.  MATH = (question8 + question9 + question10)/3
    b.  VERBAL = (question6 + question 11 + question12 + question13)/4
    c.  JOCK = question7
Now normalize these scores by assigning the values 5, 3, and 1
to each variable as these calculations give results from 1 to 2.49, 
2.5 to 3.49, and 3.5 to 5, respectively.

3.  Using the chi square statistic, determine whether or not there is
any correlation between a student's professional preference (question
9 on the survey) and his/her MATH, VERBAL, and JOCK normalized scores.
For instance, is there a relationship between MATH score and professional
preference?  And so forth for each of the other two.

Be sure that your output is formatted so that it will fit on an
80-character screen for viewing.  Moreover, be sure that all 
variables and their values are clearly labeled.  Hand in a hardcopy 
of your output, with the answers to question 3 circled on the listing.
