primarily a point-and-click
software, SPSS also has
a command syntax language.
PSPP is very similar to SPSS. It has the data and

has a layout that is almost identical to SPSS. Its option and output
windows also look very

convenient analysis of sampled data.
PSPP has far fewer statistical analysis capabilities than SPSS. It currently has the

Like with SPSS, PSPP

functions to create new variables.
- Descriptive statistics, cross tabs and other data
- t-tests (one sample, independent samples and paired

- Chi-square and binomial tests
- Bivariate correlations
- Linear regression
- Factor analysis
- Reliability analysis
- ROC curves
Unfortunately PSPP can’t do much more than that (yet).
Although PSPP would be an adequate alternative to SPSS
for some users, it wouldn’t be an adequate alternative for
