## Performing a MANOVA in SPSS

*April 25th, 2006*

Ivy sent us an e-mail about investigating the interaction effect of independent variables. MANOVA (multivariate analysis of variance) is a statistical procedure that allows you to determine if a set of categorical predictor variables can explain the variability in a set of continuous response variables.

In SPSS you can perform a MANOVA as follows:

- Choose **Analyze** -> **General Linear Model** -> **Multivariate**.

- Move the **DVs** (dependent variables) you want to examine to the **Dependent Variables box**.

- Move any **categorical IVs** (independent variables) to the **Fixed Factor(s) box**.

- Move any **continuous IVs** to the **Covariate(s) box**.

- Click **OK** and there you have your output.

If you have any more questions about MANOVA or ANOVA, submit your questions!

1.James G. Shi | August 17th, 2006 at 9:17 pmThanks for your explanation. I am now using SPSS 12.0. There is no Multivariate under Gnenral Linear Model, only Univariate.

Do you know what is wrong? Thanks.

2.andris | August 18th, 2006 at 12:56 amHello James G. Shi,

Since we do not have that version on our hands, I cannot tell you for sure. From what I have found in Google, the function has a different place in SPSS 12:

“nothing has been withdrawn from SPSS 12,

but ANOVA and MANOVA are no longer

available from the menus. They can be

accessed from command files, see

Help > Command Syntax Reference and

select Commands.”

I hope that helps you. If not, I would advise you to contact SPSS Support.

Thanks a lot for your information. I have found the Syntax for MANOVA according to your direction.

Blessings!

4.Pindaro | February 8th, 2007 at 10:46 pmDo you want us to go crazy? Where is the MANOVA in SPSS 14?

5.Doug Hsieh | February 28th, 2007 at 11:44 amHow can conduct a multivariate analysis of variance with step-down MANOVA in SPSS 13? I have 4 dependent variabls and a four levels of independent variables like race. Thanks.

6.Charlane Pereira | March 6th, 2007 at 11:00 amwhat are continuous variables?

7.Charlane Pereira | March 6th, 2007 at 11:00 amwhat are continuous IVs?

8.nat | May 14th, 2007 at 5:42 amwhy do we use manovas? is it if there is more than one dependent variable or idependent variable? thanks for your help

9.Russell | May 15th, 2007 at 5:04 pmI might be wrong, but it seems to me that the student version does not support MANOVA. Is this what you guys are experiencing as well? I only see the following scenario: listed Analyze -> General Linear Model -> Uniriate. If anyone can help me out with how to run MANOVA in a student version or if it is supported, I would be thankful to find out.

10.Russell | May 20th, 2007 at 2:37 pmgraduate pack will solve the problem listed above. The student pack does not support MANOVA application.

I have version 13 of SPSS and was blocked for a while because i thought i need to use commands to run MANOVA. you made my day. From Tunisia

12.Lindita | March 9th, 2008 at 2:10 pmI have the SPSS version 11. I was wondering how to perform MANOVA on this version. There is no “multivariate” option. Thanks.

13.Suresh | March 17th, 2008 at 4:31 amHi

I am comparing the two post operative protocols for 2 groups of patients, Group 1 will receive protocol 1 and group 2 will receive protocol 2. I am taking repeated measurements at 3rd, 6th and 8 weeks.

Please guide me in selecting the statistical method to find out differences between 2 protocols. Can i use Multivariate analysis of variance?

Thank you for your help in advance

14.elizabeth | April 2nd, 2008 at 12:46 amHello,

When we enter say the Dependent Variable into the DV box? How do we enter the levels of the DV? For example, Stress with two levels, level A andlevel B.

Also the same for Independent variables, with say three levels, say Geogprhaical area, CIty, Regional and Remote.

Thankyou in advance.

15.Ram Viswanathan | April 11th, 2008 at 4:37 amCan somebody kindly tell me how to do Canonical Analysis in SPSS. I have only version 11.

16.gladys vint | May 7th, 2008 at 9:00 amCould anyone tell me the steps to use to run a Two-way MANOVA using the SPSS Graduate Pack?

I have 1 fixed IV with 3 levels, then another repeated IIV (time) and 3 Dependant variables.

17.Luke | June 27th, 2008 at 1:44 pmMANOVA uses more than 1 independent variables

18.Gabriela Ilie | September 18th, 2008 at 6:40 pmHi,

Does anybody know ho to perform a Roy-Bargmann on SPSS version 16 (MAC version)? Thanks a million!
