Answer:
A. The vertical distance of a roller coaster from the ground changes with respect to its horizontal distance from the beginning of the ride.
Answer:
The correct option is (c).
Step-by-step explanation:
Correlation coefficient is a measure of the strength of the linear relationship between two variables.
It ranges from -1.0 to 1.0.
- A correlation coefficient closer to 1.0 indicates that there is a strong positive linear relation between the variables.
- A correlation coefficient closer to -1.0 indicates that there is a strong negative linear relation between the variables.
- A correlation coefficient closer to 0 indicates that there is no linear relation between the variables. But some other form of relation might exist.
If the correlation between two variables is close to 0, we can conclude that a scatter plot would show no straight-line pattern, but there might be a strong pattern of another form.
Thus, the correct option is (c).
