Q:
# the correlation coefficient for the ages of drivers in a driver safety class and the number of traffic violations they have received is -0.61How are the ages and numbers of violations related?A. as age increases, violation increasesB. as age increases, violations remain the sameC. as age increases, violations decreasesD. There is no association between the two

Accepted Solution

A:

A correlation coefficient is always a value in between -1 and 1

The closest a coefficient to -1, the correlation is a strong negative correlation

The closest a coefficient to 1, the correlation is a strong positive correlation

The closest a coefficient to 0, there is no correlation at all

The coefficient -0.61 shows a strong negative correlation

This means that the relationship between the age and the violation is an inverse relationship; as age increases, violation decreases

Answer: option C
