Short Course
Power calculations for researchers
The reason why the NWU wishes to offer the course is to give individuals the necessary tools to perform, interpret and report power calculations on a specific research topic. There is an increasing demand for individuals being able to perform power calculation. Power calculations plays an integral role in quantitative research, therefore by enhancing power calculation knowledge the quality and the ethicality of research outputs will improve.

Purpose of the course:

This short course aims to equip participants with the skills necessary to perform own power calculations according to studies aimed to answer a specific research question. The participant will gain knowledge on how to select a proper power calculation, perform it using available software tools, interpret the results and report power calculations in a protocol.
