The meaning of a given correlation coefficient depends on how it is applied. Introduction to Correlation Research The PowerPoint presentation contains important information for this unit on correlations. Correlational research is research designed to discover relationships among variables and to allow the prediction of future events from present knowledge. The 3 research assistants, who were the registers nurses worked in these area. 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?
