(j) Replicate the random assignment process, under the null distribution, once:
- Check the Show Shuffle Options box (slide the bottom scroll bar to the right). Notice the cards have been set up to match the cards you used.
- Press Shuffle to examine an outcome resulting from one random assignment of the subjects to the treatments under the null hypothesis that the yawn seed didn’t make a difference.
- Notice that the applet does what we suggested: Shuffles the 50 cards and deals out 34 for the “yawn seed” group and 16 for the "no yawn seed group," separating blue cards (yawners) from green cards (non-yawners) within each group.
- Group A will now have some of its original blue cards (with the dark blue top edge) and some of the blue cards that used to be in Group B and so forth.
- Check the Show table box on the left. The applet also determines the 2×2 table for the simulated results. Take a screen capture of this simulated "could have been" two-way table ("Most Recent Shuffled Two-way Table") and paste it into your lab report.
