This method illustrates random assignment, as participants are assigned to groups based on chance rather than any pre-existing characteristics or criteria. Random assignment helps to ensure that differences in the two groups are not due to anything other than the manipulation being tested, which strengthens the internal validity of the study. Statistical significance refers to the probability that the findings are not due to chance, and is determined through analysis of data. Random sampling refers to the process of selecting participants from a population in a random and representative way, and is not relevant to this scenario. Double-blind observation refers to a method in which both the researcher and the participant are unaware of whether they are in the experimental or control group, and is also not relevant here.
