Data Input for Sample Size is a table of 5 columns     Each row contains data from a separate study     Col 1 = probability of Type I error (α)     Col 2 = power (1-β)     Col 3 = reference mean or expected average of the two groups     Col 4 = reference Standard Deviation (SD) or expected background SD     Col 5 = Critical Difference (tolerable level) for equivalence Data Input for Bioequivalence Analysis is a table of 5 columns     Each row contains data from a separate study     Col 1 = sample size (per group or number of pairs)     Col 2 = reference mean or mean of reference group     Col 3 = reference Standard Deviation or Standard Deviation of reference group     Col 4 = Difference (mean of test group - reference mean)     Col 5 = probability of Type I error to be used for power analysis Sample Size :      Analysis :
