What is the purpose of the control condition in an experiment?

To provide a standard of normal behavior for comparison (correct)
To manipulate the independent variable
To ensure random assignment of participants
To determine the dependent variable

Which type of control condition involves administering a placebo?

Random control condition
No-treatment control condition
Experimental control condition
Placebo control condition (correct)

In an experiment, what role does the no-treatment control condition play?

It ensures blinding of participants
It acts as the experimental group
It provides a baseline for comparison without any treatment (correct)
