Which TABLES option(s) would be used to eliminate the

row and column counts and just see the frequencies and percents?

A. norowcount nocolcount
B. freq percent
C. norow nocol
D. nocounts

Check Answer
Answer: C

注解:RPOC FREQ statement用于生成Frequency Table。题目要求不显示Row Percent和Column Percent这个统计量,这仅需要在TABLES statement后加上NOROW和NOCOL选项,程序为:
proc freq data = dataset;
tables region * product / nocol norow;
run;
输出的结果为:

Frequency
