Dr.Gillespie has used random assignment, which means that she has randomly placed participants into either Group A or Group B. This increases the chances of both groups being similar at the beginning of the experiment, which is a key aspect of experimental control. Placebo control and blind experimentation refer to different types of experimental design, neither of which are directly related to how participants are assigned to groups.
