This differs from an a priori test, in which these comparisons are made in advance.

This differs from an a priori test, in which these comparisons are made in advance.

If increasing the sample size is genuinely cost prohibitive, perhaps accepting 90% power for a difference of 6.5, rather than 5, is acceptable. This differs from an a priori test, in which these comparisons are made in advance. Note that you use #1 (independent samples) when the correlations come from different samples and #2 (dependent samples) when the correlations come from the same sample. Also provides a complete set of formulas and scientific references for each statistical calculator.
