Answer / sandhya
PROC UNIVARIATE gives more descriptive statistics such as
skewness, kurtosis, Q_PLOT and so on. If you are looking
for an indepth analysis of the data, like clustering,
association tree,..., we start with PROC UNIVARIATE.
If we are looking for some simple results like sum mean SD
and to find extreme values we use PROC MEANS as it takes
less of machine time than PROC UNIVARIATE.

Answer / srinivas,korasavada
with proc univariate you can genarate histogrmes(graphs)
for particular variables.you can't with proc means.

Answer / ashis
Both procedure produce descriptive statistics.By proc uni
variate, by default it produce all the statistics(some time
not all required) but in proc means it is possible to
request the statistics that we want.
ex---proc means data=xyz mean max sd;
run;*it would produce statistics of above which we've
mentioned;

Answer / srinath rao
Proc MEANS:
By default proc mean calculate the discriptive statistics
only on all numeric variables available in given dataset
and that to it shows only 5 statistics .if u want u can
see more statistics....
N,MEAN,STD,MIN,MAX
Proc UNIVARIATE:
It provides data summerization tool ,High resolution
graphic displays and information on the distribution of
numeric variables.
By using Histoghram statement we can develope high
resolution graphs also..

Answer / puspendra
I am agree with Sandhya. However we use "Proc Univariate"
when we want to know from which distributions the data are
(it involves mean, var, coeff of variation, Skewness,
Kurtosis, Histogram, PPplot,QQplot etc.)

Answer / pratik
Proc Mean gives information about stastical values of
numeric varaible like mean,max,min,standard dev etc.here
you can give CLS also to restrict the limit.
Proc Univariate used to predict the distribution of single
variable. basically we use this to know whether the
distrubution is symmetric,flat or picked.
basically we can come to know skweness and kartous.

Answer / prr
Proc Means: 1. Proc means produces descriptive statistics
for the numeric variables across all observations and with
in group of observations.
2.Proc means provides N,Mean,Min,Max,STD for the numeric
variables by dafault.
3.in Proc means we have By,Class,Var statements.
Proc Univariate:1. Proc Univariate produces statistics for a
single variable.
2.Proc Univariate provides
normal,Plot,skweness,kurtosis,median,std,mode for the variables.
3.in Proc means we have By statement and Var Statement only.

Answer / prasad
1)proc univariate gives detailed reports of statas
2)proc means gives summeriged reports of statas
3)Both are worked on continous varibles
