The study data | The quick route: one call per dependent variable | Step by step, if you prefer control | 1. Check the assumptions | 2. Plot with automatic test selection | 3. Factorial designs: the Aligned Rank Transform | 4. Descriptives | Into the manuscript | Where to go next

The idea: scale x dependence x assumptions | recommend_test() as the decision helper | Fitting and reporting the recommended models | Next steps

Session setup | Example data | Check assumptions | Create a plot | Produce a reporting sentence | Next steps

What is available | Scoring | Item columns must be numbers | Declaring the response range | Adding scores to the data | Verify the mapping before you trust the scores | Incomplete responses | Internal consistency | Your own instruments | Sickness over time | Onward

The two macro modes | Tables | Reproducible values | The one-call bundle
