In other words, on average, students tended to feel that other students felt the same way they did about the death penalty. To test this hypothesis, self-other difference scores needed to be computed. Difference scores were computed separately for students and professors. The number of years at Hope was then correlated with each of these difference scores. 184 reflects the number of subjects and p reflects the probability level.
Larger samples are likely to produce statistically significant results.
Each subject is counted in only one cell. The number in each cell reflects the number of people in that cell. Don't worry about what a Chi Square value is. For now, look at the p value associated with the Chi Square. This p value indicates a significant relationship between the false consensus effect and being surprised.
