In SPSS, how can I conduct repeated measures MANOVA?
In SPSS, GLM and MANOVA fit repeated
measures MANOVA models. GLM is supported by the
point-and-click menu (click Analyze, then General Linear
Model, and then Repeated Measures); MANOVA
does not have a point-and-click menu, and requires
syntax. MANOVA produces a messy output in text form as
opposed to the table format in GLM.
Suppose two dependent variables were measured three times:
x1 through x3 and y1 through
y3. There are two (between-subject) factors: gender
(male) and race (black). The
GLM syntax for this model is:
WSFACTORS subcommand names the
within-subjects factors (dv and trial) and
specifies the number of levels (repetitions) for each factor.
If you prefer MANOVA, use the following syntax to obtain
equivalent results:
In MANOVA, the minimum and maximum values of each factor
should be specified (e.g., the value of black ranges from
1 through 4). Many options are available for both commands, specifying
various types of MANOVA. For details, see the syntax reference
included in SPSS (click Help, then Command Syntax
Reference).
For more about statistical and mathematical software, email the UITS Stat/Math Center, visit the center's web page, or phone 812-855-4724 (IUB) or 317-278-4740 (IUPUI). The center is located in Bloomington at 410 N. Park Avenue, and is open for consultation by appointment Monday-Friday 9am-5pm.
