A Researcher Decides to Collect Some Data to Test the Hypothesis

Multiple Choice

A researcher decides to collect some data to test the hypothesis that playing violent video games is related to violent behaviour. They ask a group of parents from a local elementary school to estimate two things over the last six months: how many hours per week of violent video games their children played, as well as the number of violent incidents they can recall their children being involved in. Which of the following is not a limitation inherent to this design?

A) causal conclusions cannot be drawn
B) the social desirability bias might affect the estimates provided by the parents
C) the results might not generalize beyond whatever age are represented in these data
D) these data will be very time consuming to collect (relative to other methods)
E) none of the above are limitations inherent to this design
