Just to note the existence of rainbow plots in the module, which are certainly the most informative way of plotting your data. Have a look here

Just to note that barplots with error bars are discouraged by, for example, Nature journals because they break a number of important rules : they don't show the data, and they don't show the distribution. In jamovi you can plot your data, add violin plots to show shape and boxplots to show summary s...

I would strongly support the inclusion of robust standard errors. They allow researchers to work with data that are heterogeneous, even when the underlying factors that cause the clustering cannot be measured or even specified. That is, they allow us to work with the messy reality of real world data...

The Wilcoxon Mann-Whitney test has an inbuilt measure of effect size! If you look at the title of Mann and Whitney's original paper, it's clear : 1.Mann, H. B. & Whitney, D. R. On a Test of Whether one of Two Random Variables is Stochastically Larger than the Other. Ann. Math. Statist. 18, 50–60...

I cannot stress how important robust variance estimation is in real life. The problem with traditional statistical methods is that they assume a uniform population to sample from. In fact all populations are lumpy. There are clusters of people who are more similar than they would be in a uniform pop...
