The research design can be visualized as shown in Figure 3.9, where the curved arrow represents the expected correlation . Descriptive Research and Correlational Research The main objective of descriptive research is to create a snapshot of the current state of affairs whereas correlational research helps in comparing two or more entities or variables. Predictive correlational studies predict the variance of one or more variables based on the variance of another variable (s). what are the uses of correlational research?

Scatterplot Illustrating a Correlation of +1.00(Figure 15.1), Prediction Using a Scatterplot (Figure 15.2), Multiple Regression Technique that enables researchers to determine a correlation between a criterion variable and the best combination of two or more predictor variables Coefficient of multiple correlation (R) Indicates the strength of the correlation between the combination of the predictor variables and the criterion variable Coefficient of Determination Indicates the percentage of the variability among the criterion scores that can be attributed to differences in the scores on the predictor variable Discriminant Function Analysis Rather than using multiple regression, this technique is used when the criterion value is categorical Factor Analysis Allows the researcher to determine whether many variables can be described by a few factors Path Analysis Used to test the likelihood of a causal connection among three or more variables Structural Modeling Sophisticated method for exploring and possibly confirming causation among several variables More Complex Correlational Techniques, Scatterplot Illustrating a Correlation of +1.00 (Figure 15.3), Prediction Using a Scatterplot(Figure 15.4), Scatterplots Illustrating How a Factor (C) May Not be a Threat to Internal Validity (Figure 15.7), Circle Diagrams Illustrating Relationships Among Variables(Figure 15.8), Problem selection Choosing a sample Selecting or choosing proper instruments Determining design and procedures Collecting and analyzing data Interpreting results Basic Steps in Correlational Research. \ 7 ! 0]&AD 8>\`\fx_?W ^a-+Mwj3zCa"C\W0#]dQ^)6=2De4b.eTD*}LqAHmc0|xp.8g.,),Zm> PK ! &Z&
