Question: In France in the fall of 2005, many communities of immigrants from the Middle East and North Africa experienced a great deal of violence, particularly car burnings, committed by their young people. Social science research can help to diminish or avoid such violence. Consider the following hypothetical research on the French riots: Of the cities that shared this demographic, Marseilles was one of the few that saw relatively little violence. A researcher wants to compare Marseilles with Lyons, a city that saw a great deal of violence, to determine which characteristics may have moderated violence in Marseilles, specifically among high school students. Can she use random selection? Explain. Can she use random assignment? Explain.
