Variables in Experiment Design Quiz

Variables you manipulate to affect the outcome of an experiment (correct)

Variables that represent the outcome of the experiment

Variables that are randomly assigned to treatment groups

Variables that are held constant throughout the experiment

To randomly assign subjects to treatment groups

To ensure the control group receives no treatment

To balance, group, and block experimental units so they are relatively homogeneous (correct)

To replicate the experiment under controlled conditions

The treatment group is replicated, while the control group is not

The treatment group is assigned randomly, while the control group is not

The treatment group has varying characteristics, while the control group does not

The treatment group receives the experimental treatment, while the control group receives no treatment (correct)
