In controlled experiments, researchers userandom assignment(i.e. participants are randomly assigned to be in the experimental group or the control group) in order to minimize potentialconfounding variablesin the study. For example, imagine a study of a new drug in which all of the female particip...
patients are given a short verbal explanation of the study and give verbal agreement if they wish to take part (we seek fully informed consent 6-48 hours later), and the study drug packs are pre-randomised and stored in the facility where PPCI is undertaken (to minimise any delay in using...
