Final Answer :
True
Explanation :
Random assignment is a crucial component of true experimental design as it helps to ensure that participants are similar across treatment conditions, which decreases the likelihood of confounding variables and helps to establish causal relationships. This helps to control for many threats to internal validity, such as selection bias and history effects. Therefore, random assignment is a hallmark of a true experimental design.
