!Interpret data with caution. The coefficient of variation (CV) for this estimate is between 30 and 50 percent.
‡Reporting standards not met. Either there are too few cases for a reliable estimate or the coefficient of variation (CV) is 50 percent or greater.
¹Students were asked which of the following best described them: "heterosexual (straight)," "gay or lesbian," "bisexual," "I am not sure about my sexual identity (questioning)," "I describe my sexual identity in some other way," or "I do not know what this question is asking." Students who selected "I do not know what this question is asking" are considered to be missing the sexual identity variable and thus excluded from the analyses.
NOTE: Respondents were asked about carrying "a weapon such as a gun, knife, or club." In the question asking students about carrying a weapon at school, "on school property" was not defined for respondents. Race categories exclude persons of Hispanic ethnicity. Detail may not sum to totals because of rounding and the suppression of cells that do not meet National Center for Education Statistics reporting standards.
