Answer

Explanation:

Step1: Observe data trend

As hours of exercising increase (2, 3, 4, 4, 5), hours of playing video - games don't follow a clear upward or downward pattern in a strong way. Also, as the hours of exercising increase, the hours of playing video - games seem to generally decrease in a non - very strong manner.

Step2: Determine correlation type

Since the general trend is that as one variable (hours of exercising) increases, the other (hours of playing video - games) decreases, it is a negative correlation. And because the relationship is not very strict and clear, it is a weak negative correlation.

Answer:

weak negative correlation
