Increasing effect size and sample size create similar results: less overlap of the two graphs. The difference is: A. Larger effect size creates skinnier graphs, while larger sample size moves the graphs away from each other B. Larger effect sizes moves the graphs away from each other, while larger sample size reduces their standard deviation C. Larger effect size increases standard deviation of the graphs, while larger sample size decreases the standard deviation D. Larger effect sizes moves graphs away in one direction, while larger sample sizes move them in the other direction
