Register“Forced BE” 101 [Power / Sample Size]
Dear Helmut,
Much pleasure with your reply.
Is it a thumb rule? how it should be calculated?
Yes, on getting posthoc analysis, i found three aspects what you said:
After experiment, it came to know that
1. CV getting lower
2. GMR close to 1
3. No dropouts/withdrawls (though prior consideration of 10% dropouts)
Much pleasure with your reply.
❝ study planned for 90% power: The chance to obtain a post hoc power of ≥95% is ~35%.
Is it a thumb rule? how it should be calculated?
❝ It only means that
❝ – the CV was lower and/or
❝ – the GMR closer to 1 and/or
❝ – you had less dropouts than assumed.
