Statistical Tests of Percent Differences Among Execution Actors
Electric Chair: Among Executioners, a majority (63%) was OK with executions using the electric chair. Among Hard Abstract Supporters, only 43% were OK with such executions. Among Soft Abstract Supporters, only 29% were OK with this method of execution. According to the Chi-Square test, these differences are statistically significant. The Sig. value is less than .05. With a Phi coefficient of .26 and an Eta Squared of .07, the effect size of approving this method of execution exerts slightly below medium effect on execution roles (intended actions). Eta Squared=.09 indicates a medium effect size.
When Soft Abstract Supporters and Hard Abstract Supporters were analyzed separately using the Chi-Square test with correction for continuity (2 X 2 table), the difference between them was also statistically significant. With a Phi coefficient of .15 and an Eta Squared of .02, the effect size of approving this method of execution exerts small effect on execution roles (intended actions). Eta Squared=.01 indicates a small effect size.
