Management
and policy analysis involve decision making about complex
phenomena:
- Should
a web databank be implemented to assist in implementing
welfare to work policies?
- Will
a gun buy back program lower homicide rates?
- Would
a school voucher system improve education for the poor?
- Are
safety inspection programs effective at reducing highway
injuries and fatalities?
Good
decision making is based on good data. Sample survey and
experimental design techniques aid in getting good data.
Empirical methods, primarily statistical tools, are used in
designing data capture, obtaining useful information from
data, and presenting results convincingly to various
audiences. Statistical tools include probability modeling
and regression analysis. Statistical software enables
empirical methods to be applied.
