Aggressiveness A recent study evaluated elementary age children for aggressiveness. This study found that the children who played video games were more likely to engage in aggressive or violent play at school.
 
  The researchers said the difference was statistically significant.
 
  a. Briefly explain what statistically significant means in this context.
  b. The news media reported that this study proved that playing computer games causes children to be aggressive or violent. Briefly explain why this conclusion is not justified.
  c. But perhaps it is true. We wonder if playing computer games can lead to aggressive or violent behavior in elementary school children. We find 50 young children whose families volunteer to participate in our research. Design an appropriate experiment. (You need not explain how to randomize.)

Question 2

If paired data plotted on log-log paper fall close to a straight line, we would expect a parabola to provide a
  good fit for the data.
 
  Indicate whether the statement is true or false
