Which statement correctly describes a simple hypothesis?
Which statement correctly describes a simple hypothesis?
- It does not specify the direction of the relationship between variables.
- It predicts the relationship between multiple independent and dependent variables.
- It predicts the relationship between one independent variable and one dependent variable. (correct)
- It involves variables that cannot be manipulated.
What distinguishes a directional hypothesis from a non-directional hypothesis?
What distinguishes a directional hypothesis from a non-directional hypothesis?
- Directional hypotheses depend solely on dichotomous variables.
- Directional hypotheses predict that no relationship exists.
- Directional hypotheses specify the direction of the relationship between variables. (correct)
- Directional hypotheses predict the existence of a relationship between variables.

Study Notes
Hypothesis Types
-
Simple Hypothesis: Predicts a relationship between one independent and one dependent variable. Example: Children exposed to virtual reality will experience less pre-operative anxiety.
-
Complex Hypothesis: Predicts a relationship between two or more independent and/or dependent variables. Example: Mothers' heartbeats vs. soft music on premature infant physiological parameters, and feeding tolerance.
Hypothesis Directionality
-
Directional Hypothesis: Predicts the direction of the relationship between variables. Example: Patients receiving an educational program on healthy diets will have higher dietary knowledge scores than those who don't.
-
Non-Directional Hypothesis: Doesn't specify the direction of the relationship.
Variables
-
Attribute Variables: Cannot be manipulated, examples include age, health beliefs.
-
Dichotomous Variables: Nominal variables with only two categories or levels. An example is gender (male/female).
