Question

Since 2000 the Montana County Sheriff's Department has instituted a special team of officers to apprehend drug dealers and drug couriers along a major interstate that runs through the Northwest portion of the county. Recently, representatives of the local chapter of the NAACP in Montana County have approached the Sheriff and other representatives of the county claiming that the special unit is bias against black vehicle occupants. In particular, NAACP representatives have argued that a higher frequency of black vehicle occupants have been stopped as opposed to non-black vehicle occupants. Moreover, the NAACP representatives claim that, in some cases, a higher frequency of black vehicle occupants have had property seized as opposed to non-black vehicle occupants. In an effort to avoid a potential lawsuit (which could be politically damaging to the Sheriff who is up for re-election, and who captured well over 57 percent of the black vote in his last election), the Sheriff requests that the Department's data division investigate the nature of the traffic stops. All traffic stops by race of occupant were obtained from video monitors located in the cruisers of each officer.

Identify one independent variable? Identify one dependent variable? Identify one control variable? What is the management problem? What is the hypothesis?

This has nothing to do with Annova.

Answer 1

Answers:

One Independent Variable: Type of Vehicle, Age or Gender of Offender.

One Dependent Variable: Frequency of inspection per hour.

One Control Variable: The hours of inspection/daily duty hours of officers remain same or constant.

Management Problem: The cases of black people offender checking and stopping should be done by black officers in police and similarly for the white people. This will increase the faith of citizens in non-discrimination among the same race.

Hypothesis: Average number of cases of black vehicle occupants have been stopped are higher than the non-black vehicle occupants.
