If so, share your PPT presentation slides online with PowerShow.com. Predictive correlational studies predict the variance of one or more variables based on the variance of another variable (s). Disadvantages explains why case studies are now out of vogue Subjective: Researcher decides What to look for or ignore What to record or not record What is important or not What clues to follow or drop, Descriptive Research Design Case-Series Design Simple descriptive account of interesting characteristics seen in a group of people Short time period Important descriptive role as a precursor to designing other research studies to: Evaluate causes Explanations of observations Acknowledges observed characteristic bias, Descriptive Research Design Cross-Sectional Design Also called Survey, Prevalence, Incidence, Epidemiologic Studies Diagnose or stage a disease Analyze data collected on a group at one time period Subject and information obtained in a short time frame Usefulness of new or current diagnostic procedures What is happening Establishing norms Gain insight into a topic or learn peoples perceptions (surveys) Most common research design in nursing, Non-experimental Quantitative Research Descriptive Correlational Design First: Describes variables Second: Examines relationships amongst these variables Does not infer cause-and-effect relationships Facilitates the identification of many interrelationships in a particular situation Situation may have occurred or is currently occurring No attempt to control or manipulate the situation, Non-experimental Quantitative Research Correlational Design Primary purpose is the examination of relationships Examine relationships between 2 or more variables No manipulation of variables Determine if a relationship exists between variables None, weak, moderate, or strong Determine type of relationship between variables Positive relationship or negative relationship, Correlational Research Design Case-Control Design Retrospective in nature Presents phenomenon linked to past phenomenon: What has happened?

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.

ANCOVAs are useful for these types of studies. The most commonly used inference test is a t-test for differences between means. Correlational studies are used to assess if a relationship exists between two variables. Now customize the name of a clipboard to store your clips. The variable about which the prediction is made is called the criterion variable. A correlation reflects the strength and/or direction of the relationship between two (or more) variables. 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.
