Simple, Complex, Directional, Non-Directional, and Null
Types of hypotheses
100
Older patients are more likely to fall than younger patients.
Directional Hypothesis
100
An abstract term systematically invented by researchers; more complex than a concept.
What is a construct?
100
Start with theory and this to make predictions about the phenomenon. Used in quantitative research.
What is deductive reasoning?
200
Data that is based on narrative, obtained by conversations with participants and the exploration of behavior, culture, etc.
What is qualitative data?
200
This hypothesis expresses an absence of relationship between two variables. (What is an example of this?)
Null Hypothesis
200
There is a relationship between diet and the development of high cholesterol.
Non-Directional Hypothesis
200
Abstract terms of human behavior and characteristics.
What is a concept?
200
In qualitative studies, researchers use data to develop a theory “rooted in the participants’ experiences.”
What is inductive reasoning
300
Open ended questionnaires, group interviews, fieldwork, etc.
Methods of qualitative data collection

400
Women who exercise and have a diet rich in Ca, compared to those who do not, will have a higher bone density.
Complex Hypothesis
400
Commonly used in nursing research to explain specific areas of practice, such as stress, comfort, etc. (Ex: Kolcaba’s Comfort Theory)
Middle-Range Theory
400
If a theory is valid, then certain outcomes can be expected.
