Answer:
Elimination of covariation of cause and effect
Step-by-step explanation:
Covariation of cause and effect involves establishing that there's a direct relationship of cause and effect between variables, In this cause, television violence and aggressive behavior in children. Covariations of cause and effects makes known that the cause had a measurable effect. What occurs here is that the researchers tries to show a causal relationship between variables. By not showing that, for example (from the question), children who watches television violence behaves aggressively and vice versa leads to elimination of cause and effects.
