data have;
input Animal age weight;
cards;
1 11 10
1 21 10.2
1 31 10.21
1 41 10.22
1 45 10.45
1 50 10.6
2 43 11
2 45 11.3
2 49 11.35
2 60 11.3
2 65 12.2
2 70 12.5
2 76 12.65
2 80 13
2 95 14
2 105 16

 ;

 

and i need to obtain the mean of the observations, please note that the animal number 3 is alone, so i need to use this exac value to create a table like this:

 

Animal Weight_Avegare
1 10.28
2 12.53
3 10.00

 

Thank you very much

the correct command is:

proc means data=have noprint;
class animal;
var weight;
output out=want1 mean(weight)=mean;
run;

proc sql;
create table want2 as
select animal, mean(weight) as mean_animal
from have
group by animal
order by animal;
quit;

Thank you very much

Use the CLASS or BY statement in proc means/univariate/summary or a PROC SQL.
Here's a sample of the two ways.

proc means data=have noprint;
class animal;
var weight;
output out=want1 mean(weight)=mean;
run;

proc sql;
create table want2 as
select animal, mean(animal) as mean_animal
from have
group by animal
order by animal;
quit;

Animal mean_animal
1 1
