Norsk versjon av denne nettsiden.
jamoviguiden is available in English or Swedish. It contains brief, accessible guides (with pictures) of commonly used procedures in jamovi. To keep the content short, no (or little) description of the assumptions behind the statistical tests and how to interpret the results is described. When you get started, it's often easy to explore on your own.
To learn more about jamovi and statistics, the (free!) e-book ”Learning statistics with jamovi” by Danielle Navarro and David Foxcroft is recommended.

From SPSS to jamovi
Quite a few of us are used to using SPSS in our work and are a little scared to switch to another software because it always took time and effort to get acquainted with a new software. Now might be a good time to switch because SPSS is also introducing a new interface with version 26 which at least requires getting used to something new and learn it. Why not take a little bigger step and learn jamovi? jamovi does not entail the incredibly high license costs of SPSS (from $ 1290 / year for Base Package) and can be a first step on the road to R. jamovi tries to use an interface that is relatively similar to the one in SPSS, the result version is more transparent and can be easily transferred to text processing (copy-and-paste with [mostly] keep formatting).
Comparison of analyses: provides an overview of which analysis functions are available in SPSS and the respective functions in jamovi.
Side-by-side: Shows a side-by-side comparison of how something is done in SPSS and in jamovi.
From jamovi to R
Use of jamovi syntax in R
First, you have to enable the syntax mode by pressing the properties icon in the top-right corner. Set a tick at syntax mode in the properties window.
Close the properties with the arrow-icon at the top-right .
|The main window changes to text mode and you can run analyses and afterwards right-click on the command the appears at the top of each analysis to export or copy the syntax.|
Alternatively, you can write syntax directly. To do this, open R or RStudio and type the command:
If you want to use SPSS files, you have to load the library «foreign» that loads SPSS files:
Afterwards you are ready to analyze your data. Typically, you have to load a dataset first. Do this (if you have a CSV file) by using the command («sep» has to be set to the separator between data cells, e.g., ",", ";", etc.):
> data = read.csv("data.csv", header = TRUE, sep = ",")
or for SPSS data using the command:
> data = read.spss("data.sav", to.data.frame = TRUE)
The road ahead
To learn more about R you can use two excellent websites by Danielle Navarro. The first is "Learning statistics with R" and has psychology students who use R in their first method course as the main target group. On this page you will find a PDF and a bookdown version that was the basis for «Learning statistics with jamovi» (mentioned above).
The second resource "R for Psychological Science" is still under construction and aimed more at someone who has taken at least one research method class and would like to learn to use the R programming language in their own work. This site also has a strong focus on the tidyverse methodology of Hadley Wickham.
