Answer: B, a positive correlation.
Explanation: Positive correlation happens when two variables measured move in the same direction.
For example:
1- If (First Variable) Increases then (Second Variable) Increases.
2. If (First Variable) Decreases then (Second Variable) Decreases.
In this particular case, the variables were:
a) Adolescents who watch violent content on television.
b) Adolescents who engage in more violent behavior.
The results indicated that adolescents who watch more violent content on television also tend to engage in more violent behavior than their peers. Therefore, this is an example of positive correlation.
