Study Notes
Understanding Hypotheses in Psychology
- A hypothesis is a testable statement regarding the relationship between two or more variables.
- It serves as a specific prediction of expected outcomes in research studies.
Types of Hypotheses
-
Directional Hypothesis:
- Specifies the expected direction of the relationship between variables.
- Example: Increased coffee consumption leads to significantly higher energy levels.
-
Non-Directional Hypothesis:
- Indicates that a difference exists but does not specify the nature of that difference.
- It implies a general change without detailing how groups will vary.
-
Two-Tailed Non-Directional Hypothesis:
- Similar to non-directional but emphasizes variation in both directions.
- Example: There will be a difference in recall ability between children and adults without specifying if one group will perform better.
Clarifying Hypothesis Concepts
- Hypotheses are always statements, not questions; they provide clarity and focus to research investigations.
