- 2. •JASP stands for Jeffrey’s Amazing Statistics Program in recognition of the pioneer of Bayesian inference Sir Harold Jeffreys. •This is a free multi-platform open-source statistics package, developed and continually updated by a group of researchers at the University of Amsterdam. •JASP is a free, open-source program that includes both standard and more advanced statistical techniques with a major emphasis on providing a simple intuitive user interface supported by the University of Amsterdam, Netherlands.
- 3. • It is designed to be easy to use, and familiar to users of SPSS. It offers standard analysis procedures in both their classical and Bayesian. • JASP generally produces APA Style results tables and plots to ease publication. • In contrast to many statistical packages, JASP provides a simple drag and drop interface, easy access menus, intuitive analysis with real-time computation and display of all results. • All tables and graphs are presented in APA format and can be copied directly and/or saved independently. • Tables can also be exported from JASP in LaTeX format
- 4. JASP Installation • JASP can be downloaded free from the website • https://jasp-stats.org/ and is available for Windows, Mac OS X and Linux. • Pre-installed Windows version that will run directly from a USB or external hard drive without the need to install it locally. • The JASP application is written in C++ and QML, using the Qt toolkit. • The analyses themselves are written in R and use many packages from CRAN. For Previous versions • https://jasp-stats.org/previous-versions/ • Comparison of JASP and SPSS • https://jasp-stats.org/2017/11/01/jasp-vs-spss/
- 5. Open Data from other Sources • 1. Create a Data file in excel in .csv or SPSS file .sav format • 2. In JASP, open these files using In main Menu Open -> Computer -> Browse enter then select the file which is to be handle in JASP • 3. To open already used file Open -> Recent files -> select JASP or CSV file • 4. To open sample files given in JASP Open -> Data Library
- 6. •Save/Save as: Using these options the data file, any annotations and the analysis can be saved in the .jasp format •Export: Results can be exported to either an HTML file or as a PDF •Data can be exported to either a .csv, .tsv or .txt file • Sync data: Used to synchronize with any updates in the current data file (also can use Ctrl-Y
- 7. • In the Data Preferences section users can: • • Synchronize/update the data automatically when the data file is saved (default) • • Set the default spreadsheet editor (i.e. Excel, SPSS etc) • • Change the threshold so that JASP more readily distinguishes between nominal and scale data • • Add a custom missing value code
- 8. •In the Results Preferences section users can: •• Set JASP to return exact p values i.e. P=0.00087 rather than P<.001 •• Fix the number of decimals for data in tables – makes tables easier to read/publish •• Change the pixel resolution of the graph plots •• Select when copying graphs whether they have a white or transparent background
- 9. • In the Interface Preferences section users can now define a user font and pick between two different themes; a light theme (default) and a dark theme. The preferred language currently supports English • In the Advanced Preferences section, most users will probably never have to change any of the default settings. • JASP has a streamlined interface to switch between the spreadsheet, analysis and results views. • The vertical bars highlighted above allows for the windows to be dragged right or left by clicking and dragging the three vertical dots • The individual windows can also be completely collapsed using the right or left arrow icons
- 11. • The Add notes menu provides many options to change text font, colour size etc. You can change the size of all the tables and graphs using ctrl+ (increase) ctrl- (decrease) ctrl= (back to default size). • Graphs can also be resized by dragging the bottom right corner of the graph. • As previously mentioned, all tables and figures are APA standard and can just be copied into any other document. • Since all images can be copied/saved with either a white or transparent background. This can be selected in Preferences > Advanced as described earlier.
