Jordan Is a Developmental Psychologist Who Studies Bullying and Aggression

Jordan is a developmental psychologist who studies bullying and aggression in elementary school students. Her days often consist of spending time in the schoolyard with the children and making careful notes of their interactions. She pays particular attention to incidents of bullying in the schoolyard and is trying to find personality characteristics that are associated with bullying. In her most recent study, she found that being a bully is negatively correlated with academic performance at the 0.05 level of significance.
-Which of the following is widely considered the greatest limitation in Jordan's experiment

B) Jordan does not know the children well enough to make inferences about their behaviours.
C) Jordan cannot reliably explain any patterns of behaviour she might observe.
D) The setting where Jordan makes her observations is contrived and relatively artificial.
