To use Equation for deciding on a sample size for a pilot study, we must first choose values for γ and π.By convention, we could adopt a confidence level of 95% (analogous to the level commonly chosen for confidence intervals) or choose the confidence level in accordance with the severity of the issue that we want to detect. Problems with a prevalence of 5% will be identified (with 95% confidence) in a pilot study including 59 participants.
