I want to create a new row for each student with the sum of sums and the average of the mean. My data looks like this:
(there are more students, not just these two)
Student DomainNumChar Sum Mean
1 1 17.0000000 0.5666667
1 2 24.0000000 0.6857143
1 3 25.0000000 0.8333333
1 4 24.0000000 0.8000000
1 5 13.0000000 0.5200000
10 1 25.0000000 0.8333333
10 2 22.0000000 0.6285714
10 3 23.0000000 0.7666667
10 4 20.0000000 0.6666667
10 5 13.0000000 0.5200000
and I need it to look like this:
Student DomainNumChar Sum Mean
1 1 17.0000000 0.5666667
1 2 24.0000000 0.6857143
1 3 25.0000000 0.8333333
1 4 24.0000000 0.8000000
1 5 13.0000000 0.5200000
1 . 103.000000 .68114286
10 1 25.0000000 0.8333333
10 2 22.0000000 0.6285714
10 3 23.0000000 0.7666667
10 4 20.0000000 0.6666667
10 5 13.0000000 0.5200000
10 . 103.000000 .68304762
How would I make that happen? Thanks
Hi campjabn,
One way I thought of is as follow if you don't have to do it in one data step:
data students;
input Student $ DomainNumChar $ Sum Mean;
cards;
1 1 17.0000000 0.5666667
1 2 24.0000000 0.6857143
1 3 25.0000000 0.8333333
1 4 24.0000000 0.8000000
1 5 13.0000000 0.5200000
10 1 25.0000000 0.8333333
10 2 22.0000000 0.6285714
10 3 23.0000000 0.7666667
10 4 20.0000000 0.6666667
10 5 13.0000000 0.5200000
;
run;
proc sql;
create table student_sum as
select student, "." as domainnumchar, sum(sum) as sum, avg(mean) as mean, 99 as ord
from students
group by student;
quit;
data students;
set students student_sum;
run;
proc sort data = students out = students (drop = ord);
by student ord;
run;
The following is the output:
Hope this helps somewhat!
Do you need a dataset or a report?
If you need a dataset, try
data want;
_sum = 0;
_mean = 0;
do _n_ = 1 by 1 until(last.student);
set have;
by Student;
output;
_sum = sum(_sum, sum);
_mean = sum(_mean, mean);
end;
call missing(DomainNumChar);
Sum = _sum;
Mean = _mean / _n_;
output;
drop _:;
run;
