Which one of the following would most likely have a positive linear correlation coefficient?
A. temperature of a refrigerator compared to the number of items inside of it
B. amount of money spent on baby food as a child ages
C. length of a driveway compared to number of cars owned
D. distance driven in a car compared to the hours spent driving
this question is not clear please send clear question
In this question, we are to select which of the options best answer the question.
What we are dealing with in the question is the coefficient of correlation. We want a correlation. coefficient that is positively linear.
Correlation talks about the extent of agreement between the data points involved.
So basically, what we want here are the two terms that are mostly related to one another.
A has no relationship between the two quantities. There is actually no relationship between a refrigerator’s temperature and the number of items in the refrigerator.
B , all things being equal, when a child ages , the amount spent of baby food decreases.
This shows a kind of negative correlation between the two terms
C basically has no relationship between the term/. The number of cars owners does not dictate the length of the driveway.
D. Yes, we have a positive linear relationship here. The longer you drive, the longer the distance covered.
