ABSTRACT
A fter you evaluate your univariate data analysis and feel confident that you have variables with good distributions, it is now time to begin investigating the bivariate relationships you proposed in your research questions and hypotheses. Bivariate data analysis assesses the association between two variables. If you are interested in studying three or more variables at a time, then multivariate analysis is required (see Chapter 9). Remember, if for some reason any of your variables approximate a constant-that is, almost everyone has selected only one or two of the values for that variable-then you must eliminate them from further analysis. For example, when 90 percent of the people who completed the questionnaire agree or strongly agree that they are satisfied with their current job, then job satisfaction is no longer a variable in your study unless the sample size is very large.
