Question

1. The results from a research study indicate that adolescents who watch more violent content on television also tend to engage in more violent behavior than their peers. The correlation between amount of television violence consumed and amount of violent behavior is an example of a _____ correlation.

   		positive
   		negative
   		zero
   		curvilinear

Answer 1

Correlation coefficient (positive, negative) defines direction of relationship, either positive or negative. A positive correlation coefficient means : as the value of one variable increases, the value of the second variable increases and as one decreases the other decreases. Whereas, a negative correlation coefficient indicates that as one variable increases, the other decreases, and vice-versa.

In this case increase in one varaible results in increase of the other variable,

therefore,

it is an example of a positive correlation
