Power calculations to determine sample and replication of population

TUBARIAZ — Thu, 08 Jun 2023 21:12:07 GMT

I am working on a research design and the experimental population needs to be replicated in specific numbers of groups. While analyzing the power of the experiment to determine sample size via power explorer for two independent sample means, I only get the sample size for both groups. What to do if I want to convert that sample size in an appropriate number of replicates?

This might be easier to work out in the DOE platform.

Try using Custom Design. Build your experimental structure, and then Under the Design Evaluation>Power Analysis outline bar, you can get an idea of how much power the design requires given assumptions about RMSE, and effect sizes for each model term.
