4. needs

not subject to experimental
manipulation
Studies which is unethical to
manipulate
Research which is not practically

Developmental research design
Epidemiological design

7. Descriptive research design-
features
Observes, describes and document
Occurs in natural settings
Help to gain more information about

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