Kane (2025) as a Power Paper
Kane ( 2025 ) makes several suggestions to help researchers make a compelling case for null results. These are also helpful action items to maximize statistical power .
Meyvis and van Osselaer (2018) discuss regression adjustment in the context of experiments. Clifford, Sheagley, and Piston (2021) show huge boosts in power of the pre-post design; Jordan, Ollerenshaw, and Trexler ( 2025 ) validate their findings. Lakens (2022) offers a broader perspective on sample size justification beyond statistical power .
5 Practical Rules of Thumb for Power & Sample Size
Statistical power and sample size calculations can feel overwhelming when you're planning a study. While specialized software gives you precise numbers, having some practical rules of thumb helps you quickly assess whether your study design is in the right ballpark.
The Concise Guide to Statistical Power
Why Statistical Power Matters Understanding statistical power is crucial because it: Helps you design studies that can actually answer your research questions Prevents wasting resources on underpowered studies Reduces the risk of missing important effects Improves the reliability and reproducibility of research findings Common Pitfalls to Avoid 1.
A practical guide to understanding and implementing statistical power analysis in your research.
Statistical power calculations revisited
These approaches enable A/B testing tools to provide more realistic and informative assessments of statistical power . By incorporating beliefs about the distribution of true impacts, they can better inform experiment design decisions such as traffic allocation and duration by leveraging the relative power of different metrics.
Comprehensive guide to statistical power analysis. Learn about Type II errors, effect sizes, a priori vs post-hoc analysis, and how to conduct power analysis in Python and R.
Striking findings from 2025
In frequentist statistics, power is the probability of detecting an effect (i.e. rejecting the null hypothesis) given that some prespecified effect actually exists using a given test in a given context. In typical use, it is a function of the specific test that is used (including the choice of test statistic and significance level), the sample size (more data tends to provide more power ), and ...
