Which best describes what 'correlations' are?
a method where participants' behaviour are directly observed by resarchers
a method which involves participants directly reporting answers to questions
a method to show the relationship between co-variables
Which type of correlation does C show?
Positive correlation
Negative correlation
No correlation
Which type of correlation does A show?

Negative correlation
No correlation
The more track athletes practice, the less time it takes them to finish the race.
Positive correlation
Negative correlation
No correlation
A measure of the extent to which two factors vary together, and thus of how well either factor predicts the other. The mathematical expression of the relationship, ranges from -1 to +1
scatterplot
survey
correlation
observation
case study
The principle in this method is that some variables co-vary-that is, when one variable changes, the other variable changes as well.
co-parent variables
correlational studies
field experiment
lab experiment
When two variables increase and decrease together.
Strong Correlation
Positive Correlation
Negative Correlation
Weak Correlation
Variable 1: Amount of fried chicken eaten (in ounces) Variable 2: Feelings of fullness (self-assessed on a 1-10 scale) Between these two variables, there is probably
a positive correlation
a negative correlation
no correlation
an illusory correlation
A positive r-value shows a positive correlation.
True
False
This correlation coefficient indicates no correlation at all.
(a)
What is the primary aim of a correlational study?
To determine cause and effect
To investigate the relationship between co-variables
To test the effectiveness of an intervention
To explore participants' subjective experiences
A scattergraph with points forming an upward trend indicates:
Negative correlation
