Jim Crow laws were a collection of state and local statutes that legalized racial segregation. Named after a Black minstrel show character, the laws—which existed for about 100 years, from the post-Civil War era until 1968—were meant to marginalize African Americans by denying them the right to vote, hold jobs, get an education or other opportunities. Those who attempted to defy Jim Crow laws often faced arrest, fines, jail sentences, violence and death.
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.
