What are the attributes in a research study?
Attributes refer to the characteristics of the item under study, like the habit of smoking, or drinking. So ‘smoking’ and ‘drinking’ both refer to the example of an attribute.
What two attributes must an experiment have to be called a true experiment?
True experiments must have at least one control group and one experimental group, though it is possible to have more than one experimental group. The variable that the researcher has control over is called the independent variable.
Can all causal research hypotheses be studied why or why not?
No, not all causal research hypotheses can be studied. In order to study a causal hypothesis a true experiment needs to be conducted. In order to have no confounds there has to be complete control of the experiment which limits generalizability.
What aspects of an experiment allow tests of causal relationships?
Well-designed experimental research studies allow researchers to to test causal relationships. This is because experiments allow for tests of causal relationships by manipulation of the IV(s).
What makes a causal relationship?
A causal relation between two events exists if the occurrence of the first causes the other. The first event is called the cause and the second event is called the effect. A correlation between two variables does not imply causation.
How would you describe a causal relationship?
What is a Causal Relationship? A causal relationship exists when one variable in a data set has a direct influence on another variable. Thus, one event triggers the occurrence of another event. A causal relationship is also referred to as cause and effect.
What does causal relationship mean in research?
A causal relationship is when one variable causes a change in another variable. These types of relationships are investigated by experimental research in order to determine if changes in one variable actually result in changes in another variable.
