Power analysis - What is this?

• Power analysis for group size

  • MDAR, NIH, CONSORT, ARRIVE

  • A statement addressing how (and if) an appropriate sample size was computed.

  • If we find a statement about power analysis, then SciScore expects to find the following items (randomization, blinding);

  • Example: Sample size was based on estimations by power analysis with a level of significance of 0.05 and a power of 0.9.

  • Example: Because this was a pilot study, a formal power calculation was not required.
