Contributing labs and statistical power

As of February 2023, 75 unique labs from 37 countries on all populated continents have registered their interest in the CLIMR project. Europe and North America are well-represented, while we would love to see additional collaborators in South America, Africa, Asia, and Oceania. Feel free to recommend this project to fellow researchers you know, especially from underrepresented parts of the world. Click here if you want to join as a contributing lab.

Statistical power

The figure below illustrate the statistical power of the CLIMR project.

Current status: 106 labs (September, 2022)

Statistical power for each experiment with 75 labs each collecting 100 participants, assuming 1% heterogeneity across labs. Vertical dotted lines represent the Soderberg et al’s (2014) meta-analytic effect size estimate (.475) and a conventionally small effect size (.20).
