Study Notes
Definition
- A hypothesis is a proposed explanation or assumption made about a phenomenon or problem that can be tested through scientific investigation.
- It is a educated guess that provides a framework for further investigation and experimentation.
Characteristics
- A hypothesis should be:
- Clear and concise
- Specific and testable
- Falsifiable (can be proven or disproven)
- Based on existing knowledge and research
Types of Hypotheses
- Null hypothesis: A hypothesis that states there is no significant difference or relationship between variables.
- Alternative hypothesis: A hypothesis that states there is a significant difference or relationship between variables.
- Directional hypothesis: A hypothesis that specifies the direction of the expected relationship between variables.
- Non-directional hypothesis: A hypothesis that does not specify the direction of the expected relationship between variables.
Functions of a Hypothesis
- Guides the research design and methodology
- Provides a framework for data collection and analysis
- Allows for the testing of assumptions and predictions
- Helps to identify variables and relationships that are relevant to the research question
Importance of Hypotheses
- Helps to clarify the research question and objectives
- Provides a basis for making predictions and testing assumptions
- Allows for the evaluation of the results and conclusions
- Enhances the validity and reliability of the research findings
