3.4 Navigating the jamovi Interface

Once you open jamovi, you will see a spreadsheet-like layout. Your data appear in rows and columns, similar to Excel or Google Sheets.

The main difference is that jamovi is designed for statistical analysis. It does not only store data; it also helps you define variables, run analyses, and view output.

I recommend watching this short video by Alexander Swan on navigating the jamovi interface so you can become familiar with the layout and basic menus. Some demonstrations online may use a Mac or include extra modules, so the screen may look a little different from yours.

The Data Area

The data area is where you see the dataset itself. Remember the basic structure:

  • each row is one , such as one participant, person, case, or response;
  • each column is one , such as age, condition, test score, or group.

This structure seems simple, but many analysis problems begin when data are not organized this way.

The Data Tab

The Data tab is where you work with the dataset itself. This is where you can do things like:

  • add or rename variables;
  • edit variable information;
  • check measure types and data types;
  • compute new variables;
  • transform variables; and
  • create filters.

You do not need to understand all of these tools yet. Later chapters will walk through computing variables, transforming variables, reverse-scoring items, creating scale scores, and using filters.

For now, know that the Data tab is where you go when something about the dataset itself needs to be checked or changed.

The Analyses Tab

The Analyses tab is where you run statistical analyses. For example, this is where you will eventually find options for descriptives, frequencies, t-tests, ANOVA, correlation, regression, and other analyses.

For this chapter, we are not focused on running analyses yet. Still, it is useful to know that jamovi separates data work from analysis work:

  • Data tab → set up, check, clean, and prepare the dataset
  • Analyses tab → run analyses and create output

The Results Panel

When you run an analysis, jamovi displays the results in the output or results panel. One nice thing about jamovi is that the output updates as you change options.

This can be helpful because you can see immediately how different choices affect the output. It also means you should be careful: if you click an option accidentally, your output may change.

Modules

jamovi can be extended with . A module adds analyses or tools that are not included in the base version of jamovi.

For this book, we will mostly use tools already available in jamovi or common add-on modules when needed. If a chapter requires a module, I will tell you.
