Flashcards
Non-directional Hypothesis
Non-directional Hypothesis
A hypothesis that does not predict a specific direction of the relationship between variables. It simply states that there is a relationship.
Alternative Hypothesis
Alternative Hypothesis
A hypothesis that predicts a relationship between variables. It states that there is a connection and possibly suggests how they are related.
Null Hypothesis
Null Hypothesis
A hypothesis that states there is no relationship or difference between variables. It is often the opposite of the alternative hypothesis.

Study Notes
Hypothesis Types
- Non-directional hypothesis: does not specify the direction or presence of a relationship between variables.
- Alternative hypothesis (research hypothesis): predicts a relationship among variables.
- Null hypothesis: states there is no relationship between variables.
Research Questions
- Research questions explore variables and relationships in a study.
- Questions should be clear, specific, realistic, and meet study objectives.
- They're suitable for exploratory and descriptive studies.
