A test for the Difference in Proportions tested the following null hypothesis: There is no
difference between children’s CBVS Prosocial/Care Justification Choices for stories that
involved physical victimization and the proportion of children CBVS Prosocial/Care
Justification Choices for stories that involve relation victimization.
Of the 316 responses to the physical Story Form of Victimization scenarios, 115 were
Prosocial/Care Justification Choices (sample p = 0.363924). Of the 316 responses to the
relational Story Form of Victimization scenarios, 72 were Prosocial/Care Justification Choices
(sample p = 0.227848). The estimate of the difference in the proportion of children’s
Prosocial/Care Justification Choice responses when the story involved physical victimization and
the proportion of children’s Prosocial/Care Justification Choice responses when the story
involved relational victimization was 0.136076. The hypothesized difference in proportion of
zero does not lie within the 95% CI (0.0657001, 0.206452). Therefore, zero is not a plausible
value for the difference. Thus, I reject the null hypothesis and I conclude that there is a
significant difference between the proportion of children’s Prosocial/Care Justification responses
for stories involving physical victimization and the proportion of children’s Prosocial/Care
Justification responses for stories involving relational victimization. Thus, I conclude that
children were more likely to choose Prosocial/Care Justification Choices when the story involved
physical victimization than when the story involved relational victimization. See Table 6.3.2.1.
