Statistical Analysis in JASP: An Update to the Students’ Guide by Mark Goss-Sampson

Mark Goss-Sampson’s manual “Statistical analysis with JASP: A guide for students” explains how to perform frequentist analyses in JASP. This manual has recently been updated to JASP 0.10.2.

The revised guide illustrates the workflow of the new interface in JASP 0.10.2 and discusses the new functionality. Figure 1 shows how the manual explains the new interface scaling.

The revised guide also explains the more extensive “Preferences” options, illustrated in Figure 2.

The guide includes an updated Descriptives section, which now includes the Interquartile Range (IQR), the Median Absolute Deviation (MAD), and the Shapiro-Wilk test.

In the new guide, the ANOVA section has been updated as well: the Sidak post-hoc test has been added, the explanations about the non-parametric ANOVAs have been extended (as is shown in Figure 3), and, for the two-way ANOVA section, post-hoc test for interactions have been incorporated.

Finally, brand new sections in the guide are devoted to the Two-Way Repeated Measures ANOVA and ANCOVA. The sections include explanations of the input and output options, as illustrated in Figure 4 for the case of the ANCOVA.

The updated guide is available on the JASP Materials page (click here to go directly to the PDF). We hope and expect that this manual will be helpful to teachers, students, and anybody who wants to use JASP for statistical inference. If you have any suggestions for improvement, feel free to let Mark know!
