Random assignment is the technique that ensures that personal characteristics that might affect the outcome of the experiment are divided proportionally among the participants in the different groups, making groups equivalent. This means that the researcher allocates participants to different groups randomly, reducing the risk of any group having a disproportionate number of participants with certain characteristics that might bias the results. Dependent variables are the outcomes that are being measured in the experiment, independent variables are the factors that are being manipulated or controlled in the experiment, and statistics are the tools used to analyze and interpret the data collected in the experiment. However, none of these options specifically address the technique of ensuring equivalent groups in an experiment.
