Give an example of two variables that are (or you would expect to be) strongly positively correlated, and (b) say why they are strongly positively correlated.

For this assignment, please address the following prompts. Your examples should NOT be simply numerical examples (i.e. there must be some context to the examples).

1) (a) Give an example of two variables that are (or you would expect to be) strongly positively correlated, and (b) say why they are strongly positively correlated.

2) (a) Give an example of two variables that are (or you would expect to be) weakly negatively correlated, and (b) say why they are weakly negatively correlated.

3) (a) Give an example of two variables that are not correlated because they are independent, and (b) say why they are independent.

4) (a) Give an example of two variables that are not correlated, but are dependent, and (b) say why they are not correlated and dependent.
