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.

The Nature of Correlational Research. Descriptive correlational design is used in research studies that aim to provide static pictures of situations as well as establish the relationship between different variables (McBurney & White, 2009).

Looking back in time to detect causes or risk factors for the presence or absence of an outcome Example: Case-Control Studies Cigarette smoking lung cancer People with lung cancer = cases People without lung cancer = controls Differences between groups = smoking, Correlational Research Design One Group Designs: Single Group Descriptive design : no random selection of subjects Convenience or volunteer sample Examine characteristics of a single group Natural setting Measurements made about the group Subjects serve as own control Measure group X 1, X 2, or more Still one group EXAMPLE: Satisfaction surveys one group over 12 month time period - Use the resulting descriptions to draw conclusions about that groups satisfaction scores, Correlational Research Design One Group Designs: Time Dimension Interrupted Time Series Involves more than one pre and post test measurement Equal number of measurements before and after the intervention The time periods must be constant and equal Longitudinal Time Series Follows one group to examine and measure changes in same subjects over an extended time period, Correlational Research Design One Group Designs: Time Dimension Strengths Allows examination of sequences and patterns of change over both single time period Interrupted time periods Weaknesses Multiple measurements over an extended period Subject drop out Threatens instruments validity & reliability Distorted data Subject keeps a copy of the survey and duplicated responses Hawthorne effect, Correlational Research Design One Group Design: Summary Correlational No random assignment Characteristics of single sample Pre test/post test Time series or multi-variant Longitudinal, Non-experimental Quantitative Research Comparative Descriptive Design Describes variables & examines differences in 2 or more groups Occurs naturally in a setting No manipulation of variables Results obtained from the final analysis are frequently not generalized to a population. Descriptive research is analytical in nature where in-depth studies help to collect information during research. A cross-sectional, descriptive and correlational research methods were employed in this study. Correlational nature is mathematical in nature.
