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

CONCLUSION

We all are working together to one end, some with knowledge and

design, and others without what they do…..
