i have reasonable expectation that residents of particular groups are using one of the fence types due to ethnic or religious doctrine. the questionnaire survey should distribute the 2 fence types (tall block wall & short pervious) fences amongst residents based on their ethnic origin and religious group. the fence type also affects the crime rate as one type of fence is more succeptible to burglary than the others. i want analysis method that can account for influences of the independent variables (ethnic groups) as well as the crime incidences
