PSPPIRE Data Editor (formerly PSPP)
PSPP is an application designed to analyze sampled data and perform descriptive statistics, T-tests, linear regression, and non-parametric tests.
The interface contains a comfortable working environment where you can build syntax and data files easily. It is possible to insert variables and cases, clear cases, jump to a particular variable or case, as well as to use a search function when dealing with large amounts of data.
You can sort cases, transpose variables, aggregate data, split files, sort cases based on various criteria (all, random sample, according to a time or case range, use variable filter), as well as weight cases.
In addition, PSPP lets you compute variables, count occurrences of values within cases, rank cases, recode data into the same variables or different ones, run pending transformation tasks, analyze frequencies, compare means, run a reliability evaluation, create ROC curves, and more.
The application is very light on the system resources, using a little amount of CPU and RAM. It has a good reaction speed and is stable. We have not come across any issues in our tests, since the tool did not hang or crash. The bottom line is that PSPP is free, and it caters to experienced users who want to analyze sampled data and perform tests in a friendly working environment.
