Question

Quizplus · Accepted Answer

Assigning participants to groups based on the order in which they arrive is not a random assignment method, and therefore may lead to biased group composition. Random assignment methods, such as coin flipping or using a random number generator, ensure that all participants have an equal chance of being assigned to any group, which increases the chances of balanced group composition and reduces the effects of individual differences or biases.
