If Your First Baby is Early, Will Your Second Baby be Early?

This post was written the week before the birth of our daughter Leanne, who finally decided to make an appearance on Valentine’s Day this year.

Nataschja is lying on our sofa, watching a series on Netflix. It is Tuesday afternoon and I am working from home.

One such reason is that the p-value can be used to silence your skeptics — that is, to discredit the null hypothesis that the experimental treatment was utterly ineffective. In the third part I will demonstrate how Bayesian hypothesis testing with JASP (jasp-stats.org) can provide a practical, principled, and easy-to-use alternative.
