CogStat is great, we know, but it is not designed for some tasks, some planned features are not available yet, or there may be some special scenarios where individual analysis software should be used. So here is our recommendation for those cases.
General purpose statistical programs
- jamovi has maybe the most nicely optimized user interface to run your statistical analyses. We recommend it as a number one option for individual analyses.
- If you need a Bayesian analysis, JASP is the most user-friendly solution to display your results.
- Spreadsheet programs, like Microsoft Excel, are not considered to be main tools for data and statistical analyses, but in fact they are quite powerful, and very useful for large part of the data analysis. LibreOffice Calc is a freely available and efficient spreadsheet software.
Specific statistical tasks
- GPower has a comprehensive list of tools for power analysis.
- Single-case study statistic packages for various conditions by John R Crawford.
- OpenMeta[analyst] for meta-analysis.
Additional options for general statistical analyses
- PSPP is an SPSS clone, meaning that it intends to be compatible with SPSS, and uses the same commands, and a similar user interface as SPSS. Although it is far from as comprehensive as SPSS, still PSPP could be appropriate for some simple tasks.
