Question

Peter observes a correlation of r = +.25 between playing violent video games and acting aggressively on the playground. This means that:

1) There is a weak positive relationship between playing violent video games and acting aggressively on the playground.
2) There is a strong positive relationship between playing violent video games and acting aggressively on the playground.
3) There is a weak negative relationship between playing violent video games and acting aggressively on the playground.
4) There is a strong negative relationship between playing violent video games and acting aggressively on the playground.

Answer 1

Peter observes a weak positive correlation of r = +.25 between playing violent video games and acting aggressively, indicating that as video game play increases, there may be a slight increase in aggression.

Step-by-step explanation:

Peter observes a correlation of r = +.25 between playing violent video games and acting aggressively on the playground. This statistical measure indicates that there is a weak positive relationship between the two variables. A weak positive relationship means that as time spent playing violent video games increases, there is a slight tendency for aggressive behavior on the playground to increase as well, although the correlation is not strong enough to confidently predict aggressive behavior based on video game use alone.
