Question

what does a positive correlation between two variables indicate?
a. as one variable increases, the other decreases
b. the relationship between the variables cannot be determined
c. the variables are unrelated
d. as one variable increases, the other also increases

Explanation:

A positive correlation means that when one variable changes (increases or decreases), the other variable changes in the same direction. For example, if we consider the relationship between study time and exam scores, a positive correlation would imply that as study time increases, exam scores also tend to increase.

Answer:

d. As one variable increases, the other also increases
