Text: Statistical Methods for the Social Sciences, 4th Ed, Agresti and Finlay


Course Description: Statistical methods commonly applied in social science research, with a single response (dependent) variable and one or more explanatory/control (independent) variable(s). Cases covered include when the response and prediction variables are of interval, nominal, and ordinal scales. Models, interpretations, and computing (SPSS) will be stressed.
