    Study Notes

    Hypothesis

    A hypothesis is a crucial component of the scientific method. It is a tentative explanation for a phenomenon or a proposed solution to a problem.

    Key characteristics of a hypothesis:

    • Testable: A hypothesis must be able to be tested and proven or disproven through experimentation and data analysis.
    • Specific: A hypothesis should clearly and concisely state the expected outcome or relationship between variables.
    • Falsifiable: A hypothesis must be able to be disproven or rejected if the data does not support it.
    • Parsimonious: A hypothesis should be simple and straightforward, avoiding unnecessary complexity.

    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.

    Functions of a hypothesis:

    • Guides the investigation: A hypothesis helps to focus the research and determine the methods and procedures to be used.
    • Provides a framework for data analysis: A hypothesis helps to identify the data to be collected and the statistical tests to be used.
    • Facilitates the interpretation of results: A hypothesis provides a basis for determining whether the data supports or rejects the hypothesis.

    Hypothesis development:

    • Based on observations: A hypothesis is often developed based on observations and preliminary data.
    • Informed by prior research: A hypothesis may be informed by previous research and studies on the topic.
    • Refined through iteration: A hypothesis may be refined and revised through the process of testing and analysis.
