I have to design a proposal in order to evaluate 'cross-racial' attitudes of young people who live in a high crime area,towards gun carrying. Can I simply evaluate attitudes, and compare them across different races, or do I need to have young people who live in a low crime area to act as a comparison or a control? Would this help me determine if it's the race or the area that effects the attitude? Also, which test would I use in either of these scenarios, I'm thinking a t-test or ANOVA? Thanks!
