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.
