Can you calculate the mean, median and mode of the following data set using data step logic? Don't use any function or procedure. 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; I have calculated the mean which i have posted in the answer section.
data study; input Subj : $3. Group : $1. Dose : $4. Weight : $8. Subgroup; x= input(Weight,5.1); datalines; 001 A Low 220 2 002 A High 90 1 003 B Low 193.6 1 004 B High 165 2 005 A Low 123.4 1 ; Why does X get truncated? X shows up as 22 instead of 220,9 instead of 90 and 19.8 instead of 198? This problem doesnt happen with the values 193.6 and 123.4. This does not happen if x is read on the 5. informat instead of the 5.1 informat
