Question

Quizplus · Accepted Answer

Block randomization is a technique used in within-subjects designs to control for both linear and nonlinear progressive errors. Linear progressive errors occur when there is a consistent increase or decrease in performance over time, while nonlinear progressive errors do not follow a straight line and can vary in direction and magnitude. Block randomization helps in mitigating these effects by ensuring that each condition is presented in a balanced order across participants, thus minimizing the impact of these types of errors on the results.
