## 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.**
