Arrange the following researches in an increasing order in terms of generalization of their respective findings:
A. Ethnographic research
B. Survey research
C. Experimental research
D. Action research
E. Case study research
Choose the correct answer from the options given below:

Correct option is C

The correct sequence of research types in terms of increasing generalization of their findings is:
1. Action research
2. Case study research
3. Ethnographic research
4. Experimental research
5. Survey research
Information Booster:
1. Action Research: Focuses on solving specific problems in a local context and is not intended for broad generalization.
2. Case Study Research: Provides detailed insight into a particular case but is limited in generalizability.
3. Ethnographic Research: Involves in-depth study of cultures or communities, offering rich, context-specific insights.
4. Experimental Research: Involves controlled conditions to determine cause-and-effect relationships, allowing for more generalizable findings.
5. Survey Research: Uses large sample sizes to collect data, providing the highest level of generalizability among these methods.
Additional Information:
· Action Research: Often conducted by practitioners to improve their own practices and typically involves iterative cycles of planning, acting, observing, and reflecting.
· Case Study Research: Useful for exploring new or unique phenomena, offering detailed contextual analysis but limited external validity.
· Ethnographic Research: Emphasizes understanding social interactions and cultural practices within their natural settings, providing deep, contextual understanding.
· Experimental Research: Uses random assignment and controlled variables to test hypotheses, providing strong internal validity and generalizability.
· Survey Research: Gathers data from a large number of respondents using questionnaires or interviews, suitable for identifying trends and making broad generalizations.
