Question

What can be said of the correlation between the brand of an automobile and its quality? The correlation is negative because smaller cars tend to have higher quality and larger cars tend to have lower quality. The correlation is positive because better brands have higher quality. If correlation is negative, an arithmetic mistake was made. Correlation must be positive. Correlation makes no sense here because "brand" is a categorical variable.

Answer 1

Answer:

The correlation is positive because better brands have higher quality

Explanation:

Positive correlation occurs when the increase in one variable brings about the increase in the other variables. There is a positive relationship between brand and quality because the better the Brand, the higher the quality of car they are to make.
