We we had fun yesterday learning about statistical hypothesis testing 😍 in my ISE 225 Foundations of Data Analysis (Engineering Statistics) class
#StatisticalInference #HypothesisTesting #ILoveTeaching

Setting alpha=0.05 means that supposed the null hypothesis is true... it will take a critical fail for you to end up with data convincing you that it isn't (and of course the DM won't let you see the roll).

Rolling a nat 1 in the real world. #DnD #hypothesistesting #statssky #experiments

Null hypothesis: mean is 0. Alternative hypothesis: mean is greater than 0. This is useless. The practical effect should be larger than gamma. Testing null hypothesis where mean=gamma with alternative hypothesis that mean greater than gamma is always allowed.

You can always calibrate your statistical test to focus on a hypothesis about what YOU deem as a practically significant effect… if you so dare. #statssky #hypothesistesting #sciencesky

Chernoff‑Stein Lemma Expanded for Composite Correlated Hypotheses

Researchers present a Chernoff‑Stein lemma for composite, correlated hypotheses, giving a single‑letter Stein exponent. The 54‑page paper was submitted on 7 Oct 2025. Read more: getnews.me/chernoff-stein-lemma-exp... #chernoffstein #hypothesistesting

In an hour and a half (12:30 UTC / 14:30 CET) I'll give a lightning talk at the online BTS conference about the tool we are putting together for standardizing hypotheses.

A formal hypothesis test in statistics is a structured method used to determine whether there is enough evidence in a sample of data to infer that a certain condition holds for the entire population.
