Question 4

The strength of the linear relationship between two interval variables can be measured by the:
A)coefficient of variation.
B)coefficient of correlation.
C)slope of the regression line.
D)Y -intercept.

Accepted Answer

The coefficient of correlation, also known as Pearson's correlation coefficient, measures the strength of the linear relationship between two interval variables. The value ranges from -1 to 1, where -1 indicates a perfect negative relationship, 0 indicates no relationship, and 1 indicates a perfect positive relationship. As such, it is the best choice for measuring the strength of the linear relationship between two interval variables.
