Research on the Results of Laboratory and Field Experiments That

Research on the results of laboratory and field experiments that examine the same variables suggests that:

A) the effect size of the independent variable on the dependent variable is very similar.
B) the impact of the independent variable on the dependent variable is marked by dissimilarity.
C) independent variables in field experiments must be manipulated differently from laboratory experiments.
D) these experiments must be conducted in similar settings for the results to be complementary.
