Questions and Answers

What is a hypothesis?

  • A definite conclusion based on extensive evidence.
  • A tentative statement predicting the relationship between variables. (correct)
  • An established fact that has been universally accepted.
  • A systematic process of investigation and research.

    • Which of the following definitions best describes a Null Hypothesis?

  • It suggests no effect or relationship between variables. (correct)
  • It asserts that one variable causes the other to change.
  • It claims the existence of a strong correlation between phenomena.
  • It indicates a direction in which a variable affects another.

    • What is a characteristic of a well-defined hypothesis?

  • It is overly complex and detailed.
  • It is based solely on theoretical concepts without practical application.
  • It is vague and ambiguous.
  • It relates to the problem statement clearly. (correct)

    Study Notes

    Objectives

    • Students will define hypothesis at the end of the lesson
    • Students will differentiate types of hypothesis
    • Students will write a well-defined hypothesis using given variables

    Hypothesis

    • A tentative statement of the expected relationship between two or more variables under the study

    Types of Hypothesis

    • Simple and Complex Hypothesis
    • Associative or causal Hypothesis
    • Directional or Non-directional Hypothesis
    • Null Hypothesis

    Simple and Complex Hypothesis

    • Smoking is a prominent cause of lung cancer
    • Individuals who eat more fruit tend to have higher immunity, lesser cholesterol, and high metabolism.

    Directional and Non-Directional Hypothesis

    • There is a positive relationship between years of teaching experience and job satisfaction among teachers
    • There is a relationship between years of teaching and job satisfaction among teachers

    Null Hypothesis

    • There is no relationship between smoking and the incidence of lung cancer among teenagers

    Associative and Causal Hypothesis

    • (No specific information provided)

    How to Write a Well-Defined Hypothesis

    • (No specific information provided) - Example provided

    Characteristics of a Well-Defined Hypothesis

    • States the expected relationship between variables
    • Testable
    • Derived from problem statements
    • Simple and concise

    Activity Examples (Well-defined/Not Well-Defined)

    • Chocolate is better than vanilla (NO): Subjective and not testable
    • Sleep deprivation affects cognition (YES): Testable and measurable
    • Animals adapt to their environment (NO): Too broad and not specific enough
    • Social media use causes anxiety (YES): Measurable though causation may be complex
    • Silver weapons can kill werewolves (NO): Not scientifically verifiable.

    Description

    This quiz focuses on defining and distinguishing various types of hypotheses. Students will explore simple, complex, associative, causal, directional, non-directional, and null hypotheses through specific examples and definitions. By the end, participants will write their own well-defined hypothesis using provided variables.
