Non experimental design Non experimental design Presentation Transcript

  • NON EXPERIMENTAL RESEARCH DESIGN PRESENTED BY MISS: RESHMASUZEN
  • Definition  Non experimental research design is one which the researcher observes the phenomena as they occur naturally , and no external variables are introduced.
  • needs  Human characteristics are inherently not subject to experimental manipulation  Studies which is unethical to manipulate  Research which is not practically possible to conduct experiment  Needed before an experimental study
  • TYPES  Descriptive research design  Correlational / Expost facto design  Developmental research design  Epidemiological design  Survey
  • DESCRIPTIVE RESEARCH DESIGN
  • Descriptive research design- features  Observes, describes and document  Occurs in natural settings  Help to gain more information about characteristics  Provide an impression of a situation  Do not involve the manipulation of variables  Used to develop theories, identify problems with current practice  Bias can be prevented
  • Types of descriptive research design Univarient Exploratory Comparative
  • CORRELATIONAL RESEARCH DESIGN
  • Correlational research- features  Examine change in one variable correlate with other  Correlational coefficient  Cause and effect study
  • Types of correlational study  Prospective study  Retrospective study
  • DEVELOPMENTAL RESEARCH DESIGN
  • Developmental research design Cross sectional longitudinal
  • Longitudinal studies Trends studies Panel studies Follow- up studies
  • EPIDEMIOLOGICAL RESEARCH DESIGN
  • Epidemiological research design Cohort study Case control study
  • Cohort study PEOPLE WITHOUT DISEASE EXPOSED UNEXPOSED DISEASE NODISEASE DISEASE NO DISEASE population
  • Case control Oral Contraceptives Cause Breast Cancer with breast cancer (Cases) Oral Contraceptive (Exposure) from same hospital Without Breast Cancer(control)
  • SURVEY RESEARCH DESIGN
  • Survey research study-based on nature of phenomenon under study Descriptive survey Exploratory survey Comparative survey Correlational survey
  • Survey study Written • questionnaire • opinionnaires oral • interview • Telephonic conversation electronic • Mail message • sms method of data collection
  • Advantages of non experimental research design  Closest to real situation  Suitable for nursing research  Cases in which manipulation is forbidden
  • summary  Non experimental research design Types  Descriptive  Expost/correlational  Developmental  Epidemiological design  Survey method Advantages and disadvantage
  • CONCLUSION We all are working together to one end, some with knowledge and design, and others without what they do…..
