A psychologist wants to create two groups that are as similar as possible at the beginning of an experiment. to do this, he or she should use Random Assignment.

In psychology experiments, random assignment refers to the use of chance processes to guarantee that each participant has an equal chance of being allocated to any particular group. Participants in studies are divided into several groups at random, such as the experimental group or the treatment group.

It's critical to select a sample that accurately reflects the characteristics of the population being studied in order to extrapolate the findings of an experiment to a broader population. For instance, if there are 51% women and 49% men in the population overall, the sample should represent those proportions.

Because each group in the experiment had the same participants thanks to random assignment, the groups are probably more typical of the makeup of the general population. By employing this method, psychologists may investigate complicated phenomena and advance our knowledge of the human mind and behaviour.
