Contributing labs and statistical power

A total of 110 unique labs from around the globe have registered their interest in the CLIMR project.

As of March 2020, 110 unique labs from 30 countries on all populated continents have registered their interest in the CLIMR project. Of these, 84 have already confirmed that they will participate as a contributing lab (as of April 9, 2020) and we expect that this number will increase. 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 figures below illustrate the statistical power of the CLIMR project. We are already in a very good position to make precise estimates of effect sizes.

Current status: 84 labs (April 9, 2020)

Power for each of the four experiments with 84 labs, each collecting 100 participants, assuming 1% heterogeneity across labs. The long-dashed vertical line represents the meta-analytic estimate of the effect of psychological distance on construal level found in the most recent meta-analysis on the topic (Soderberg et al., 2014; d = 0.475).

What happens if we get to 100 labs?
