Research Methods in Medicine and Health Sciences

This work will consider the types of bias that may arise in an RCT, and how it can be subjectively analysed and minimized. Bias has been described as being prejudice or inclination for or against person/s or group/s in a manner that is considered unfair [6]. This will be explored by considering bias at different points within the RCT, namely subject bias and sampling bias. Areas that will be explored within subject bias will include blind and double blind trials. Bias will also be considered with reference to sample selection, taking into consideration how certain samples may have advantages/disadvantages for RCT design methodology.
