7.1.1 Hypothesis Formation

• A hypothesis is a tentative explanation that needs to be tested
• Why is a hypothesis considered crucial in scientific research?

  Guides study design and analysis
• Match the scientific concept with its definition:

  Hypothesis ↔️ Proposed explanation for a phenomenon

  Theory ↔️ Broad explanation supported by evidence

  Law ↔️ Descriptive statement about nature
• A good hypothesis must be possible to test through observation or experimentation
• What does the null hypothesis state in scientific research?

  No significant relationship
• The goal of research is to collect evidence to reject the null hypothesis in favor of the alternative hypothesis.


  True
• A good hypothesis should be specific and state the expected relationship between the variables
• Why is falsifiability a key characteristic of a good hypothesis?

  Allows for disproof
• A good hypothesis should be specific, meaning it clearly states the expected relationship between the variables
• A hypothesis that cannot be disproven is considered scientifically valid.

  False
• What is the definition of a hypothesis?

  Proposed explanation for a phenomenon
• A hypothesis is a well-established explanation, while a theory is a tentative one.

  False
• Why is a hypothesis crucial in scientific research?

  Provides clarity and direction
• A good hypothesis must be testable through observation or experimentation.


  True
• What does the null hypothesis (H0) state?

  No significant relationship
• The goal of research is to collect evidence strong enough to reject the null hypothesis
• What is a key characteristic of a falsifiable hypothesis?

  Can be disproven by data
• A descriptive statement about a natural phenomenon is referred to as a law
• What is empirical evidence used for in hypothesis testing?

  To support or refute
• A hypothesis is a proposed explanation that can be tested through investigation
• What type of statement is a scientific law?

  Descriptive
• What are the four key roles of a hypothesis in scientific research?

  Clarity, direction, testability, planning
• A falsifiable hypothesis must be possible to disprove or reject based on data.


  True
• The goal of a researcher is to collect evidence to reject the null hypothesis in favor of the alternative
• What is a hypothesis in scientific research?

  Proposed explanation for a phenomenon
• A hypothesis provides clarity to research by defining the specific relationship between variables.


  True
• A hypothesis is an educated guess about the relationship between two or more variables
• What is the key role of empirical evidence in testing a hypothesis?

  Supports or refutes it
• A hypothesis must be falsifiable to be scientifically valid.


  True
• The alternative hypothesis proposes a significant relationship or difference
• What is a testable hypothesis?

  Explanation supported by evidence
• A hypothesis must include measurable variables to be tested empirically.


  True
• What is a testable hypothesis in scientific research?

  Proposed explanation for a phenomenon
• What does it mean for a hypothesis to be measurable?

  Variables can be quantified
• Match the scientific concept with its definition:

  Hypothesis ↔️ Proposed explanation for a phenomenon

  Theory ↔️ Broad explanation supported by evidence

  Law ↔️ Descriptive statement about nature
• A theory is a broad explanation supported by a large body of evidence
• A hypothesis provides clarity by defining the specific relationship between variables
• Order the characteristics of a good hypothesis:

  1️⃣ Testable

  2️⃣ Specific

  3️⃣ Measurable

  4️⃣ Falsifiable
• What does the alternative hypothesis (H1) propose?

  Significant relationship exists
• A hypothesis that is specific clearly states the expected relationship between variables.
