An observation table shows that preschoolers who engage in more cooperative play also receive higher peer-acceptance ratings. Which option best explains the directionality problem?
A
Labeling one variable as a predictor does not prove direction; the data still allow cooperative play increased peer acceptance and children accepted by peers had more opportunities for cooperative play.
B
Because cooperative play and peer-acceptance ratings were measured with numbers, the study automatically rules out all causal alternatives.
C
The relationship between cooperative play and peer-acceptance ratings must be explained by a third variable, so neither measured variable could ever influence the other.
D
A correlation between cooperative play and peer-acceptance ratings is invalid unless participants are randomly sampled from every grade level in the country.
