"In assessing whether their workout plan led to significant gains, the gym was advised to use a one-sided test"
June Results:
The cartoon for our 109th cartoon caption contest in June is shown above. Amongst the 38 submissions for the contest, the judges found the winning caption for the cartoon to be “In assessing whether their workout plan led to significant gains, the gym was advised to use a one-sided test.” submitted by Steve Wang from Swarthmore College. Steve’s caption can be used to discuss the difference between one- and two-sided tests (and why the gym in the cartoon might choose the former). Three honorable mentions this contest go to 1) Nayab Ali, a student at University of Texas at San Antonio for her submission: “When your sample is biased, your gains are too,” to illustrate the problems of biased sampling such as drawing data from an unusual sampling frame; 2) Chantelle Estabillo, a student at MiraCosta College for the caption “Lefty’s Gym promised gains, but they didn’t say the distribution would be so right-skewed!” for discussion of the meaning of skewness in statistics and how it differs from usage in everyday speech; and finally to 3) an anonymous submission for the caption “Not the best place for a matched pair design,” to discuss how matched pair designs that rely on bodily symmetry should still be randomized across subjects.
Thanks to everyone who submitted a caption and congratulations to our winners
