P-values are derived from a chi-square test, using a Yate’s Correction where necessary, and a Wilcoxon Rank Test was completed with a Kruskall-Wallis Correction. Percentages are out of the total number of respondents for that specific question. In this table, other race includes multi-racial. In this study, 9–11 grad includes 12th grade completion without a high school diploma.
