Question

Quizplus · Accepted Answer

True experiments require random assignment to conditions, which means that participants are randomly assigned to either the experimental group or the control group. This random assignment helps to control for extraneous variables and increases the likelihood that any differences between the groups are due to the manipulation of the independent variable, rather than some other factor. Correlational methods may be used in quasi-experimental designs, but they are not a defining feature of true experiments. Random selection from the population is also important for generalizability, but it is not a requirement for a study to be considered a true experiment.
