When examining how variables are related to one another, researchers may find that the relationship is positive or negative.
Or they may also find that there is no relationship at all.
How Does Correlational Research Work?
In correlational research, the researcher measures the values of the variables of interest and calculates a correlation coefficient, which quantifies the strength and direction of the relationship between the variables.
The correlation coefficient ranges from -1.0 to +1.0, where -1.0 represents a perfect negative correlation, 0 represents no correlation, and +1.0 represents a perfect positive correlation.
A negative correlation indicates that as the value of one variable increases, the value of the other variable decreases, while a p
