dataset new {x y} {1 2} {6 4} {7 5} data s1 s2 s3; set new; if x > 5 then output s1; if y < 5 then output s2; output; run; Choose the correct answer about s1 s2 and s3

  1. s1 and s2 have 2 observations and s3 has no observations

  2. s1 and s2 have 5 observations and s3 has 3 observations

  3. s1,s2,s3 have 3 observations

  4. s1 and s2 have 2 observations and s3 has 3 observations

B Correct answer
Explanation

The SAS data step processes 3 input observations. OUTPUT statements direct observations to specific datasets: s1 gets 2 obs (x>5), s2 gets 2 obs (y<5), s3 gets all 3 obs (default OUTPUT). However, when multiple OUTPUT statements execute for one observation, that observation counts multiple times. This creates the stated totals.
