What is the role of a null hypothesis (H0) in scientific research?
- To directly influence the outcome of the research.
- To represent an alternative theory to be tested.

Flashcards
Research Hypothesis
Research Hypothesis
A testable statement about a relationship between variables. It can be verified or falsified and is developed using current knowledge and practical resources.
Hypothesis Verifiability
Hypothesis Verifiability
A scientific hypothesis must be measurable and verifiable using statistical and analytical approaches to support or reject the proposed relationship.
Falsifiable Hypothesis
Falsifiable Hypothesis
A scientific hypothesis must be able to be proven wrong. It's not possible if the hypothesis is too vague or worded to avoid being proven wrong.

Study Notes
Research Hypotheses
- A research hypothesis (H1) is a statement about the expected outcome of an experiment or study.
- It's crucial to any experimental design, representing the core aim.
- Hypotheses are developed through inductive reasoning, starting with observations leading to theories.
- Deductive methods then refine the hypothesis to be testable, falsifiable, and realistic.
- The process begins with a problem, often a question, like "Why are cod stocks declining?".
- This broad question needs narrowing down into a testable hypothesis.
- Example hypotheses: "Over-fishing affects cod stocks," or "Reducing trawlers will increase cod stocks if over-fishing is the cause."
- A strong hypothesis predicts an outcome and involves an “If/Then” statement, defining an independent and dependent variable.
- Hypotheses must be testable and falsifiable; a scientist should consider the possibility that their hypothesis is wrong.
- Statistical tests may uncover trends, but don't offer definitive proof, as factors other than the hypothesized one may influence results.
- Hypotheses must be realistic considering current knowledge, resources, and measurement capabilities.
- A hypothesis is never proven, but can be supported or verified by evidence.
- A well-supported hypothesis builds upon further research and can potentially become a theory (e.g., Einstein's general relativity).
- The hypothesis (H1) contrasts with the null hypothesis (H0), which represents the current view.
- Key characteristics of a good hypothesis: clear language, independent and dependent variables, falsifiable, prediction of outcome, practical, and describing relationship or intervention between variables.
