Similarities Associative research Attempt to explain phenomena of interest Seek to identify variables that are worthy of later exploration through experimental research Neither permits the manipulation of variables Attempt to explore causation Differences Causal studies compare two or more groups of subjects Causal studies involve at least one categorical variable Causal studies often compare averages or use crossbreak tables instead of scatterplots and correlations coefficients Similarities and Differences Between Causal-Comparative and Correlational Research, Similarities Require at least one categorical variable Both compare group performances to determine relationships Both compare separate groups of subjects Differences In experimental research, the independent variable is manipulated Causal studies are likely to provide much weaker evidence for causation In experimental studies, researchers can assign subjects to treatment groups The researcher has greater flexibility in formulating the structure of the design in experimental research Similarities and Differences Between Causal-Comparative and Experimental Research, Steps Involved in Causal-Comparative Research Problem Formulation The first step is to identify and define the particular phenomena of interest and consider possible causes Sample Selection of the sample of individuals to be studied by carefully identifying the characteristics of select groups Instrumentation There are no limits on the types of instruments that are used in Causal-comparative studies Design The basic design involves selecting two or more groups that differ on a particular variable of interest and comparing them on another variable(s) without manipulation (see Figure 16.1), Independent Dependent Group variable variable (a) I C O (Group possesses (Measurement) characteristic) II C O (Group does (Measurement) not possess characteristic) (b) I C1 O (Group possesses (Measurement) characteristic 1) II C2 O (Group possesses (Measurement) characteristic 2) The Basic Causal-Comparative Designs, Examples of the Basic Causal-Comparative Design (Figure 16.1), Threats to Internal Validity in Causal-Comparative Research Subject Characteristics The possibility exists that the groups are not equivalent on one or more important variables One way to control for an extraneous variable is to match subjects from the comparison groups on that variable Creating or finding homogeneous subgroups would be another way to control for an extraneous variable The third way to control for an extraneous variable is to use the technique of statistical matching, Does a Threat to Internal Validity Exist?
