A
- a clear, precise, testable statement
- that states the relationship between the variables that are being investigated
5
Q
Directional hypothesis
definition
A
-states the direction of the difference/relationship
6
Q
Non-directional hypothesis
definition
A
-does not state the direction of the difference/relationship
7
Q
Variables
definition
A
-something that can vary within an investigation
8
Q
Independent variable (IV) definition
A
- aspect if the experiment being manipulated by the researcher/changes naturally (CHANGES)
- so DV can be measured

Q
Dependent variable (DV) definition
A
- variable measured by the researcher (MEASURED)
- any effect on the DV should be caused by the IV

Q
Operationalization
definition
A
-clearly defining variables in terms of how they can be measured
