Which of the following are measures of the linear relationship between two variables?
A) The covariance
B) The coefficient of correlation
C) The variance
D) Both a and b
Coefficient of Correlation
A measure that indicates the degree to which two variables are linearly related.
Covariance
A measure that indicates the extent to which two variables change together, but does not specify the nature of the relationship.
Linear Relationship
A relationship between two variables where the change in one variable is proportional to the change in another variable.
- Acquire knowledge on the principles of covariance and the correlation coefficient, including how they differ and their practical applications.
- Investigate the link among covariance, the coefficient of correlation (r), and the intensity and trajectory of linear correlations.
