How can strength of the linear relationship between two numerical variables be measured?
By definition, the strength of the linear relationship between two variables can be measured by the coefficient of correlation.
How do you determine if there is a linear relationship between two variables?
A linear relationship can also be found in the equation distance rate x time. Because distance is a positive number (in most cases), this linear relationship would be expressed on the top right quadrant of a graph with an X and Y-axis.
Is a measure of the strength of the relationship between two variables?
The correlation coefficient is a statistical measure of the strength of the relationship between the relative movements of two variables. The values range between -1.0 and 1.0.
What is a measure of the strength of the relationship between two variables?
A correlation coefficient measures the degree (strength) of the relationship between two variables. The Pearson Correlation Coefficient measures the strength of the linear relationship between two variables.
