Chapter 8.8, Problem 60S

To determine

To find whether the scatter plot of data shows a positive, negative or no relationship for speed and distance travel.

Answer to Problem 60S

The scatter plot for the speed and distance travelled has no relationship.

Explanation of Solution

Concept Used:

Correlation is the linear relationship between two quantitative variables.

There are three types of correlation

In positive correlation both the variables are in same direction.

In negative correlation when one variable increases other variable decreases and vice versa.

There is no correlation when there is no relation between the two variables.

Speed is factor that is not relatively affected of the distance travelled one can travel 100 km with a high speed and another can also travel 100 km at a very low speed. Therefore, there is no relationship.

Therefore, it has no relationship.

Conclusion:

Hence, the scatter plot for the speed and distance travelled there is no relationship.
