  • Schedule
Add to Calendar Sample Size Determination for Clinical Research 1/30/2021 9:00:00 AM 1/30/2021 3:00:00 PM Asia/Riyadh Livestream false MM/DD/YYYY


Date & Location
Saturday, January 30, 2021, 9:00 AM - 3:00 PM, Livestream, Doha, Qatar

Overview
The course helps researcher determine the sample size needed for their study. Basic theory will be explained such as confidence intervals, p-values, power of a study, design effect and more. Sample sizes for different study designs such as prevalence studies, parallel group studies, ..etc will be discussed. The course will be applied using available free resources (webpages and software) to demonstrate sample size computations.

Target Audience
