Investigating Browne's method

Obodo, Scholastica; Toher, Deirdre; White, Paul

Abstract

Results supports Browne’s procedure of pilot sample size determination. However the data reveals that the procedure underestimates and overestimates sample size. Fig. 1 shows 𝛼 and 𝛽 have no practical effect on degree of excess which increases as coverage increases from and diminishes with increasing pilot sample size. Using regression the results shows the median percentage error (MPE) at each pilot sample size and this can assist researchers make better decisions in determining pilot sample size
