Professor Kim's students designed an experiment to
investigate whether self-esteem was affected by how often she called on them when they raised their hand in class.

What is one significant flaw in their design? a) They have no independent variable. b) They have no operational definition for self-esteem. c) They have no dependent variable. d) They don't have a sample.
