In an experiment, the process of random assignment ensures that each participant has an equal chance of being in either the control group or the experimental group.
Random assignment refers to the use of random methods in psychological experiments to equalize the chances of each participant being assigned to a particular group. Participants in the study will be divided into various groups at random, such as an experimental group or a treatment group.
Tossing a coin, picking a name out of a hat, rolling dice, or giving players random numbers are just a few examples of random assignment techniques. Remember that random assignment is distinct from random selection. Random assignment describes how those chosen participants are then assigned to experimental groups, whereas random selection describes how people are picked at random to represent the greater community.
