Study Notes
Hypothesis Overview
- A hypothesis is a tentative prediction or explanation regarding the relationship between two or more variables.
Sources of Hypothesis Formation
- Hypotheses can originate from personal experience, existing literature, or theoretical frameworks.
Criteria for Testable Hypothesis
- Must entail a relational statement involving two or more measurable variables.
- Should include comparative phrases like "more than," "less than," "greater than," "different from," or "related to."
- Variables need to be operationally defined to ensure measurement.
- Hypotheses must be justifiable and align with established research findings.
Types of Hypotheses
- Directional Hypothesis: Specifies the anticipated direction of the relationship between variables.
- Non-directional Hypothesis: Indicates the existence of a relationship but does not predict the direction.
- Null Hypothesis: Asserts that there is no relationship between the independent variable and the dependent variable.
- Research Hypothesis: Serves as the alternative to the null hypothesis.
- Simple Hypothesis: Predicts the relationship between one independent variable and one dependent variable.
- Complex Hypothesis: Involves predictions about relationships between two or more independent variables and/or two or more dependent variables.
Expectations in Literature
- Hypotheses typically appear before the Methods section in research reports, often placed at the end of the Introduction or the Literature Review.
- Many studies may not explicitly state a hypothesis, particularly qualitative studies, which typically do not have a hypothesis.
Reading Hypotheses
- Directional Hypothesis: Includes a prediction about the relationship between the independent and dependent variables.
- Non-directional Hypothesis: States THERE IS a relationship without specifying any prediction.
Clarification of Hypothesis Types
- The research hypothesis serves as the alternate form of the null hypothesis, providing a contrasting statement for empirical testing.
