Dear David,

❝ ... Post-hoc power calculations may also be useful.


Post-hoc power is useless! Search the forum to find numerous discussions on that topic.
Have also a look at Helmut's lectures, especially about power and sample size estimation.
For instance this one: "Sample Size Challenges in BE Studies and the Myth of Power"

Regards,

Detlew
