1 What has to be true about the shape of a relationship in order to start talking about the correlation’s direction being positive or negative?
2 What is the difference between a weak relationship and a negative relationship?
3 What is the difference between a strong relationship and a positive relationship?
4 If we find a strong relationship in a sample from a larger population, will that relationship always hold for the whole population? Why or why not?
5 If two correlations are both positive, is the stronger one more positive (steeper slope) than the other?
