Here is the formula used for determining sample size for pilot study: Sample Size ss = Z 2 * (p) * (1-p) c 2 Where: Z = Z value (e.g. 1.96 for 95% confidence level) p = percentage picking a choice, expressed as decimal (.5 used for sample size needed) c = confidence interval, expressed as decimal (e.g., .04 = ±4)
