Question

1. what does a positive correlation between two variables indicate?

a. as one variable increases, the other also increases
b. the relationship between the variables cannot be determined
c. the variables are unrelated
d. as one variable increases, the other decreases

Explanation:

A positive correlation means that when one variable changes in a certain direction (e.g., increases), the other variable also changes in the same direction (increases). Option b is incorrect as positive correlation does determine a relationship. Option c is wrong because positive correlation shows a relationship. Option d describes a negative correlation.

Answer:

A. As one variable increases, the other also increases
