Calculating The Sample Size Required For Developing A Clinical Prediction Model The Bmj from www.bmj.com

In this article, we present a simple formula to calculate the sample size needed to be able to identify, with a chosen level of confidence, problems that may arise with a given probability. All datasets except one (francis et al., 2010) had a sample that was much larger than the sample ultimately needed for saturation, making them effective for assessing saturation. The sample size of the datasets used varied from 14 to 132 interviews and 1 to 40 focus groups.

Although it may seem like magic, behind our sample size calculator there is a methodology that validates the sample calculation. For this one, we rely on the following formula: Although sample size calculation methods for pilot studies have been proposed, none of them are directed at the goal of problem detection. 3 enter the size of …
