We won't do your homework for you. Experiment, see what you get. If there is something you don't understand, come back to us.

It depends. Usually you should have an idea of what procs you need based on what you’ve covered.

You may need FREQ, ANOVA, REG, GLM, UNIVARIATE or TTEST

proc univariate

id;

class;

histogram;

PROC UNIVARIATE tells you about the distribution of one variable, so it isn't appropriate for your question.

Have you been studying linear regression? If so, see the documentation for PROC GLM.

Look at the documentation for the MODEL statement and ask yourself, "How can I model the response variable to account for those other categorical and continuous variables?"

This has nothing to do with being a beginner in SAS. It has to do with properly formulating a question and being clear about what you're looking for and what you have. And realizing that homework is your job, not ours. We will help,but you need to clearly articulate your question AND what you've attempted - and this is more important on homework questions.

You can find video tutorials here:

and the SAS e-course on Statistics is free, see the elearning section.

Good Luck.

Hi thanks rick

i uses the following

/* 7) Does Sales amount differ among different account status, GoodCredit, and

customer age segments? */

proc tabulate data=final;

class Account_Status GoodCredit age_segment;

var sales;

table account_status, sales*(n sum mean stddev skewness);

table goodcredit, sales*(n sum mean stddev skewness);

table age_segment, sales*(n sum mean stddev skewness);

run;

/* Non parametic */

PROC NPAR1WAY data=final wilcoxon;

Class account_status;

Var sales;

Exact; *OPTIONAL;

Run;

PROC NPAR1WAY data=final wilcoxon;

Class GoodCredit;

Var sales;

Exact; *OPTIONAL;

Run;

/* GoodCredit based */

proc ttest data=final alpha=0.05;

var sales;

class GoodCredit;

run;

PROC NPAR1WAY data=final wilcoxon;

Class age_segment;

Var sales;

Exact; *OPTIONAL;

Run;
