Question

Quizplus · Accepted Answer

This method of assigning participants to conditions in a way that each condition receives an equal number of participants without considering the characteristics of the participants or their order of arrival is characteristic of a random-groups design. The key aspect here is the aim for equal numbers in each group, not the specific matching or ordering of participants, which distinguishes it from the other options.
