Question

Quizplus · Accepted Answer

The researcher is using a random assignment method by flipping a coin to determine which group each participant will be assigned to. This helps to eliminate the potential influence of experimenter bias and ensures that the two groups have an equal chance of being assigned to either group. It is not an example of monetary assignment or treatment effects, as the distribution of participants is not being influenced by any external factors or manipulations.
