We can check for negative correlation by counting the number of violations.
1. Only 2 violations out of 7 points. So, negatively correlated.
2. 3 violations and that too closely spaced. So, a rough graph helps to knoe that these are actually slightly positively correlated.
3. Only 2 violations out of 7. So, negatively correlated.
