New paper for anyone working with data:
Better data viz - for free, in few clicks.

Below, all N = 111, M = 0.04, SD = 0.27.
One-sided t-tests vs. 0 yield: t(110) = 1.67, p = .049.

Use raincloud plots. Or risk wrong conclusions!
Plot w/ @jaspstats.bsky.social today!

I agree: Stacking can be beneficial. Here is one way how that might look like in JASP (Figure 4 from the article).

The next step in empirical sciences towards transparent data visualization is the widespread adoption of raincloud plots through accessible, free software.

Whether its academia, industry, or education: Raincloud plots offer a more complete report of your data as they simultaneously show summary statistics, a density estimate, & individual data points.

With that, they beat prevalent bar charts.

Strikes are beginning, because the cuts are dire. This story has many twists and turns, but in short, Dutch universities are proposing to sacrifice certain programs like our Psychology BSc in English to hope to appease the nationalist government. This isn't done yet.

What feature(s) do you miss in JASP?
What should we add?
How may we improve your analyses and user experience?

Suppose you generated a sequence of 100 random numbers. Then one year later, you did it again. Do you think we could predict one sequence from the other? It turns out, we can!

2. Prior predictive checks. As I simulated data for my conditions (beyond assigning a prior for effect size), I got a feeling for what struck me as (un-)reasonable.
Here is a great tutorial: link.springer.com/article/10.3...

Two things helped me:

1. I browsed the literature for effects that were somewhat related and I derived a plausible/reasonable prior. Ie what are the papers closest to your novel effect? Yes, they might have done (remotely) different things, yet offer a ballpark.
