Hypothesis in Research: Types, Examples, Features & MCQs (UGC NET LIS)
Hypothesis: Types, Examples, Features, Advantages & MCQs
1. Introduction
In research, a hypothesis plays a central role in guiding the study. It provides a tentative explanation or prediction that can be tested through data collection and analysis. In fields like Library and Information Science, social sciences, and management, hypotheses help researchers focus their investigations and establish relationships between variables.
A well-formulated hypothesis not only directs research design but also helps in drawing meaningful conclusions.

2. Definition
A hypothesis is a tentative statement that predicts a relationship between two or more variables and can be tested through empirical research.
- It is a testable statement
- Based on theory or prior knowledge
- Foundation for data analysis
3. Features and Types of Hypothesis
Features of a Good Hypothesis
- Testable
- Clear and precise
- Logical
- Specific
- Simple
Types of Hypothesis
Null Hypothesis (H₀): No relationship between variables
Alternative Hypothesis (H₁): Shows relationship
Simple Hypothesis: One independent & one dependent variable
Complex Hypothesis: Multiple variables
Directional Hypothesis: Shows direction
Non-Directional Hypothesis: No direction

- Gives direction to research
- Helps in analysis
- Makes research systematic
- Tests theories
- Helps in conclusions
5. Comparison Table
| Type | Meaning | Example |
|---|---|---|
| Null | No relationship | No link between study & marks |
| Alternative | Shows relation | Study improves marks |
| Simple | One variable | Exercise improves health |
| Complex | Multiple variables | Diet + exercise improve health |
