Managers need to know the broad basis of statistical techniques in order to manage information efficiently. More importantly, they need to interpret results and to extrapolate for effective decision-making. This text aims to guide the reader through the principles of: statistical data; probability; regression and correlation analysis; forecasting; and time series analysis, emphasizing their practical applications. The authors illustrate the techniques with extensive reference to computer programs and statistical packages.
