A researcher wants to examine the relationship between viewing television violence and behaving aggressively. He has participants decide whether they would prefer to view a violent or a nonviolent film, and subsequently records the number of aggressive behaviors they show in a competitive game. The researcher cannot legitimately make a causal statement based on his findings because the study .

Lacks random assignment

Explanation:

the researcher may not Be able to establish valid causal relationships as the study lacks random assignment in that participants do not get equal opportunity of being assigned to groups. Random assignment means the researcher applies chance in assigning participants to groups such that the study is not biased and causal relationships are not affected. For example if a participant does not get to choose his group, the researcher randomly flips a coin to assign him to a group and so there is an uncorrupted result in findings
