*Nonsignificant (p > .002)

The phi coefficient was chosen to express the strength of the association in each crosstabulation, both because the coefficient can be compared across tables and because, for two-by-two tables, it has the property of registering a negative value for negative associations. The coefficient's absolute value ranges from 0 to 1, with 0 indicating no association and 1 indicating perfect association. Table 1 presents the results. To hold the overall tolerable error of the analysis to .05 or less, the maximum p value for any one crosstabulation was set at .002. The phi coefficient for each crosstabulation was significant except for two: the crosstabulation of "ending school prayer limits" and being an evangelical Bush supporter, and the crosstabulation of "ban abortion" and "improve moral values."
