Description of the Project:

In a health study to investigate an epidemic outbreak of disease (spread by mosquitoes), individuals were randomly sampled within two sectors in a city to determine if the person had the disease under study.  The response variable y was coded 1 if an individual had the disease, and 0 if not.  The three predictor variables included in this study were:

bullet

age (quantitative variable)

bullet

socioeconomic status of household (categorical variable) - three levels:

bullet

upper

bullet

middle

bullet

lower

bullet

sector within city (categorical variable) - two levels:

bullet

sector 1

bullet

sector 2

NOTE:  It is expected that the upper socioeconomic class will have the lowest disease rate among the three classes.  Hence, it is chosen as the reference class (i.e.  The class for which indicator variables x2 and x3 are coded 0)  

In this on-line workshop, you will find many movie clips. Each movie clip will demonstrate some specific usage of SPSS.

Using this data set, we will demonstrate the following data manipulation and analysis:
