RANCH 4 $68,575
SPLIT 3 $77,983

Which of the following steps created the report?
a. proc freq data=sasuser.houses;
tables style price /nocum;
format price dollar10.;
label style="Style of homes"
price="Asking price";
run;
b. proc print data=sasuser.houses;
class style;
var price;
table style,n price*mean*f=dollar10.;
label style="Style of homes"
price="Asking price";
run;
c. proc means data=sasuser.houses n mean;
class style;
var price;
format price dollar10.;
label style="Style of homes"
price="Asking price";
run;
d. proc report data=sasuser.houses nowd headline;
column style n price;
define style / group "Style of homes";
define price / mean format=dollar8.
"Asking price";
run;

The FREQ procedure cannot create the average asking price. The CLASS statement and
the VAR statement are not valid for use with the PRINT procedure. The MEANS
procedure output would have both the N statistic and the N Obs statistic since a CLASS
statement is used. The REPORT procedure produced the report.

请问从哪里看出来 asking price 是average呢，还有means procedure那个，为什么不是var condo ranch split  twostory而是var price呢~
