Answer / dupe bassey
proc means generates an output, if you want to suppress an
output, you include the noprint option.
proc summary doesnt generate an output, if you want an
output, you include the print option.

Answer / ram
1. Proc Means By default gives a Printable output,where as
summary does't.
2. If We ommit var statement in MEANS all numeric varibles
wiil be considered into analysis and it calculates
N,MEAN,STD,MIN,MAX by default.
where as Summary does't do like this if we ommit var
statement it gives only simple counts.

Answer / chiranjeevi
proc means:
When ever we are using the proc means procedure by default
it's displaying the results in output window.
syntax:proc means data=<dataset name>;
output out=<newdataset name>;
run;
proc summary:
proc summary doesnt generate an output, if you want an
output, you include and specify the print option.
syntax:proc summary data=<datasetname> print;
output out=<newdatasetname>;
run;

Answer / abhik
I just want to add one point.
Proc Print by default generate output. But Proc summary does
not. So in Proc summary either you have to mention print
option or output data set name. Otherwise you will get an
error in the log:
"
ERROR: Neither the PRINT option nor a valid output statement
has been given"

Answer / m.sivakumar
1.specifies whether PROC SUMMARY displays the descriptive
statistics. By default, PROC SUMMARY produces no display
output, but PROC MEANS does produce display output.
2.If you omit the VAR statement, then PROC SUMMARY produces
a simple count of observations, whereas PROC MEANS tries to
analyze all the numeric variables that are not listed in the
other statements.
3.If you specify statistics on the PROC SUMMARY statement
and the VAR statement is omitted, then PROC SUMMARY stops
processing and an error message is written to the SAS log.

Answer / name is no need
differences:
1.The means procedure provides the simple statistics like
N,min,max,mean ans standard deviation.
The summary procedure provides the values _type_,_freq_ and
_stat_.
2.The means procedure gives the ouput/list report by
default.
The summary procedure provides a data set instead of
output/list report
3.proc means syntax:
proc means data=data set name;
class<varible declaration>;
var<variable declaration>;
run;
Proc summary syntax:
proc summary data=data set name;
output out=<new data set name>;
class<variable declaration>;
var<variable declaration>;
run;
4.if we use Noprint and output out=.. options in proc means
it should exactly equals to proc summary.

Answer / padmasri
The major difference between Proc Means and Proc Summary is
proc means by default generates an output but proc summary
does not generate output if we specify print option in the
proc summary it will generate an output.
