This diagram categorizes various types of research based on six different criteria: objective, outcome, logic, process, inquiry mode, and concept. It highlights how research can be descriptive, exploratory, experimental, fundamental, applied, deductive, inductive, qualitative, quantitative, conceptual, or empirical depending on the approach and purpose.

1. On the basis of objective: Research is classified as:

Descriptive: Aims to describe characteristics or functions.

Exploratory: Investigates new or unclear problems.

Experimental: Tests hypotheses under controlled conditions.

2. On the basis of outcome:

Fundamental Research: Seeks to gain deeper theoretical understanding.

Applied Research: Focuses on practical problem-solving.

3. On the basis of logic:

Deductive Research: Begins with a theory or hypothesis and tests it.

Inductive Research: Develops theories from observations or data.

4. On the basis of process:

Qualitative Research: Focuses on non-numerical data, such as words and meanings.

Quantitative Research: Uses measurable data and statistical analysis.

5. On the basis of inquiry mode:

Repeats Deductive and Inductive types, focusing on the method of investigation.

6. On the basis of concept:

Conceptual Research: Based on theories and concepts.

Empirical Research: Based on observations and experiments.

Understanding these classifications helps researchers select the most appropriate method for academic, scientific, or practical investigations, ensuring that their approach aligns with their research goals and the nature of their questions.
