Question

what does a positive correlation indicate?
a. no relationship between the variables
b. both variables increase together
c. both variables decrease together
d. one variable decreases while the other increases

Explanation:

Positive correlation means when one variable increases, the other also increases. It shows a direct relationship between the two variables. For example, as study time (one variable) increases, exam scores (another variable) also tend to increase. So, option B is correct. Option A is for no correlation, option C is a negative - like (but not exactly negative) wrong concept (negative correlation is when one increases and the other decreases), and option D is for negative correlation.

Answer:

B. Both variables increase together
