A researcher finds that children who play lots of video games also tend to be aggressive with their peers at school. Explain the third variable problem and how it could influence the interpretation of this correlation. What might that third variable be?

Step 1
This can lead to a false conclusion about the relationship between the two variables, as the third variable might be the actual cause of the observed correlation. In this case, the correlation between playing video games and aggressiveness in children might be Show more…

(Third Variables). This pause-problem is a bit tougher. I want you to come up with three additional "third variables" that might explain the aggression/violent TV watching relationship. That is, list three different "Variable Cs" (and you cannot use "lack of parental supervision") that might be the true link between Variables A (aggression) and B (watching violent TV).

If the correlation coefficient is 0.45, what is the proportion of variance in one variable that is associated with the other variable? If playing video games and aggression are correlated, what are three possible directions of causality that might explain this correlation? A health psychologist studies the relationship between caloric intake and weight gain in a group of 250 adults between the ages of 25 and 40. The correlation between increasing one's caloric intake and subsequent weight gain is found to be 0.60 (p < 0.05). What does it mean to say that this particular correlation coefficient is statistically significant?
