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 designCorrelational / Expost facto
designDevelopmental research designEpidemiological designSurvey
DESCRIPTIVE RESEARCH DESIGN
Descriptive research design-features
Observes, describes and documentOccurs in natural settings Help to gain more information about
characteristics Provide an impression of a situationDo not involve the manipulation of
variablesUsed to develop theories, identify
problems with current practiceBias 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

CONCLUSION
We all are working together to one end, some with knowledge and
design, and others without what they do…..
