Random selection ensures that all individuals in the population have an equal chance of being chosen, which helps to reduce bias and increase the generalizability of the study results. Random assignment, on the other hand, refers to the process of randomly assigning participants to different groups or conditions in an experiment, which helps to control for extraneous variables. Normal distribution is a statistical concept related to the distribution of data points around a central mean, while the scale variable assumption pertains to the assumption that the measurement scales used in a study are appropriate for the research questions being asked.
