Test Defining correlational research
Agenda
1st QUESTION: What is the purpose of correlational research?
Establish cause and effect relationships
Examine the relationship that exists between two or more variables to determine if they are associated
Manipulate variables in a controlled manner
Study a single individual in depth
2nd QUESTION: What does a negative correlation indicate?
That as the value of one variable increases, the value of the other also increases
That there is no relationship between the variables
That one variable is the cause of the other
That as the value of one of the variables increases, the value of the other decreases
QUESTION 3: What is the most crucial drawback of correlational research?
Their inability to demonstrate cause and effect relationships
Its ability to predict behavior
The use of a mathematical statistic such as the correlation coefficient
Which can only be applied to aggressive behavior
QUESTION 4: What is the "third variable problem"?
The idea that only two variables can be studied at a time
The possibility that there is a third unknown variable that is truly responsible for the observed correlation
The fact that correlation always implies causation
A type of experimental research
QUESTION 5: What does a positive correlation indicate?
That as the value of one variable increases, the value of the other decreases
That as the value of one variable increases, we can predict that the value of the other will also increase
That the relationship between the variables is non-existent
That no prediction can be made
QUESTION 6: If viewing aggression on television is found to be correlated with aggressive behavior, what conclusion CANNOT be drawn?
That the two variables vary together
That there may be a third variable involved
That aggressive children may prefer violent programs
That watching aggression on television causes aggressive behavior
QUESTION 7: What is the correlation coefficient?
Mathematical statistic that represents the strength and direction of the relationship between two variables
A research method that establishes causality
A third variable that explains the relationship
An example of experimental research
QUESTION 8: What type of research has the capacity to establish a true cause-and-effect relationship?
Correlational research
Experimental research
Descriptive research
The case study
