options firstobs=1 obs=26;
data a;
input age @@;
datalines;
22 32 32 32 43 23 24 56 45 54 28 29 27 26
25 28 30 20 18 37 36 47 46
56 19 20
;
run;
proc sort data=a out=ab;
by age;
run;
options firstobs=13 obs=14;
data c;
set ab end=last;
sum_age+age;
if last then median=sum_age/2;
run;
we need observation 13 and 14 because total number of observations is n=26 when n is even we need to do mean of two observations n/2 and (n/2)+1 which is 13th and 14 th observations in this case.
let me know if you need more help... I'm still thinking about mode...will send once I get it
