Duration: 1 Day

Designed for: Anyone involved in the design of clinical trials or involved in writing clinical trial reports or manuscripts, including:

Project Managers
Medical Advisers
Medical Writers
Project Accountants

The Course is ideal for groups who have to determine their own clinical trial sample sizes without input from Statisticians as well as groups who need to understand the components to more effectively work with statisticians to determine sample size.

Description: This Course is designed to equip the participant with the essential knowledge as to the requirements of sample sizing which include the key components of power, significance and assumptions. This course is not designed to be statistical and will include no mathematics or formulae, instead this gives a practical insight into how sample sizing is done and the most effective approaches to it.

The Course is a blend of theory and practical hands-on experience using sample sizing software to compute real sample sizes and explore the various assumptions.

Participant Feedback :
I have sat through a number of presentations on medical statistics in my career, and I can honestly say this was the best.
You managed to make the subject understandable and accessible, and the feedback from all the delegates was overwhelmingly positive.
