In studying the correlation between the amount of time children watch violence on television and children's levels of aggressiveness,researchers found that a lack of adult supervision could be a third variable.To control for the third variable,researchers observed children who experienced different amounts of supervision.They made sure that for every child observed who watched a lot of violence on television and was supervised X% of the time,they also observed another child who did not watch a lot of violence on television and was supervised X% of the time.This method is called:
A)third-variable correlation.
B)matched samples.
C)matched pairs.
D)manipulation.
