Which of the follwing variables will be produced by PROC MEANS procedure?
-
n-count,mean,standerd deviation,Min and MAX values
-
n-count,frequency,mean,standerd deviation,Min and MAX values
-
frequency,cumulative frequency ,mean,standerd deviation,Min and MAX values
-
both b&c
PROC MEANS by default produces n-count, mean, standard deviation, minimum, and maximum values for numeric variables. It does not produce frequency or cumulative frequency (those are from PROC FREQ). Option A is correct despite the 'standerd' typo.
SAS's PROC MEANS, by default (with no STATS options specified), produces the descriptive statistics: N (count of non-missing observations), MEAN, STD (standard deviation), MIN, and MAX for each numeric analysis variable. Frequency and cumulative frequency are statistics produced by PROC FREQ, not the default PROC MEANS output, so the options mentioning them are incorrect, and 'both b&c' is wrong for the same reason.
