Discussion

(d) Review the results of this study and summarize what they reveal about the effectiveness of the yawn seed in for these study participants.

[Hint: You may want to come back to this part after you have completed the computer output portions of the lab,]

In particular, write a paragraph that addresses the following:

  • What are the observational units and variable for these data?
  • For what sample (and sample size) were these data collected?
  • What did you learn about the differences between the two treatment groups? (cite your numerical and graphical evidence)
  • Do the data appear to support the claim that yawning is contagious?

Side note: There is a difference between saying one treatment is effective (e.g., did most people in the group yawn) and saying one treatment is more effective than another (e.g., was the conditional proportion of success higher in one group than the other).
