Statistical Software Tutorials
The tutorials presented here comprise a general inroduction
to each software package. Each tutorial is not intended to
be a substitute for a full semester course on the topic of
interest, nor is it intended to replace the software documentation.
Complete manuals for most programs are available for check
out through the University of Texas PCL Library; you can check
their availability status through UTNETCAT.
Most materials presented in the tutorials were developed for
use in brief (three hour) lecture-format workshops, taught
every semester to interested UT students, faculty, and staff.
For details, see the ACITS training
schedule. More tutorials may be found in our World Links section.
- AMOS
- The AMOS (Analysis of Moment Structures) software program
features a powerful, yet easy to use graphical interface.
It is designed primarily for structural equation modeling
and similar analyses (e.g., path analysis, confirmatory factor
analysis), though it can also be used to fit MANOVA, MANCOVA,
ANOVA, ANCOVA, and regression models.
- HLM
- HLM (Hierarchical Linear Models) are used for analyzing
data in a clustered or "nested" structure, in which lower-level
units of analysis are nested within higher-level units of
analysis. For example, students are nested within classrooms,
which are nested within schools. While experimenters are often
not interested in the effects of a particular classroom or
school when they are examining the effects of a classroom
intervention, these units potentially have an effect on the
outcome of the study that should be accounted for in a statistical
model. The program can be used to analyze a variety of questions
using either categorical or continuous dependent variables.
- PRELIS and LISREL
- PRELIS and LISREL are designed primarily for structural
equation modeling and similar analyses (e.g., confirmatory
factor analysis and path analysis), though it can also be
used to fit ANOVA, ANCOVA, MANOVA, and MANCOVA models. Also,
it be used to perform regression analysis and some multilevel
or hierarchical linear modeling (HLMs).
- Mplus
- Mplus is primarily designed for conducting exploratory
factor analysis, confirmatory factor analysis, and structural
equation modeling. The program can also handle multiple group
analysis and multilevel SEM.
- SAS
- Over the years SAS has developed a reputation of being a
powerful and full-featured package for general statistical
analysis. The new release of SAS (version 8) has a number
of new features that promise to make SAS more user-friendly.
In particular, the current version of SAS has a substantially
enhanced windows-driven interface which allows you to point
and click your way through many tasks that previously required
knowledge of SAS programming syntax.
- SPSS
-
Getting Started: introduces readers to the SPSS for
Windows environment, and discusses how to create or import
a dataset, transform variables, manipulate data, and perform
descriptive statistics.
-
Descriptive and Inferential Statistics: describes
the use of SPSS to obtain descriptive and inferential
statistics. In this module, you will be introduced to
procedures used to obtain several descriptive statistics,
frequency tables, and crosstabulations in the first section.
In the second section, the Chi-square test of independence,
independent and paired sample t tests, bivariate and partial
correlations, regression, and the general linear model
will be covered.
-
Displaying Data: describes the use of SPSS to create
and modify tables which can be exported to other applications.
Graphical displays of data are also discussed, including
bar graphs and scatterplots as well as a discussions on
how to modify graphs using the SPSS Chart Editor and Interactive
Graphs.
-
Data Manipulation and Advanced Topics: describes the
use of SPSS to do advanced data manipulation such as splitting
files for analyses, merging two files, aggregating datasets,
and combining multiple tables in a database into an SPSS
dataset. Several advanced topics are also included, such
as the use of SPSS syntax, the SPSS Visual Basic editor,
and SPSS Macros.
