Research Hypothesis
- A Prediction about what research will find.
- It shows a relationship between Variables
eg. Consumption of sugary drinks leads to obesity.
Types of Research Hypothesis
- Null Hypothesis
- Alternate Hypotheis
- Simple Hypothesis
- Complex Hypothesis
- Associative Hypothesis
- Causal Hypothesis
- Directional Hypothesis
- Non Directional Hypothesis
1.Null Hypothesis (H0)
No relationship between two variables
Researcher tries to disapprove this hypothesis
eg. Age has no effect on mathematical ability.
2.Alternative Hypothesis (H1)
It shows relationship between two variables
Researcher tries to test this hypothesis
eg. Daily drinking green tea reduces weight
3.Simple Hypothesis
Prediction of relationship between two variables (Dependent &
Independent Variable)
eg. Daily drinking green tea reduces weight.
4.Complex Hypothesis
Prediction of relationship between two or more Dependent Variables
& two or more Independent Variables
eg. Eating more vegetables and fruits leads to weight loss, glowing
skin, and reduces the risk of heart disease.
5.Associative Hypothesis
It shows associative relationship between the dependent and the
independent variables
Relationship between variables occurs naturally without manipulation
eg. Communication skills of health care providers and cost of care
related to the satisfaction of patients
6. Causal Hypothesis
It clearly defines that the particular variable results in the change of
the other variable
eg. inhaling chalk dust causes asthma
7. Directional Hypothesis
It shows positive or negative relation (Direction) between variables.
eg. Positive relationship between extra coaching and academic
achievement
eg. Continuing Nursing Education will develop high quality of nursing
skills.
8. Non - Directional Hypothesis
It shows relation between variables but does not show direction.
eg. Teacher Student relationship influences student's learning.
