Some researchers have noted that adolescents who spend a lot of time playing video or computer games are at greater risk for depression and violence. This is an example of: a.an observational study with lurking variables that may explain the association. b.a paired data experiment, because we are studying both aggression and game playing. c.a single-blind experiment, because the subjects knew they were playing games. d.a valid conclusion, because more time yields more aggression is a positive association.
