Given N Pairs of Observations $\left( x _ { 1 } y _ { 1 } \right) , \left( x _ { 2 } y _ { 2 } \right) , \ldots \ldots \ldots , \left( x _ { n } , y _ { n } \right)$

Short Answer

Given n pairs of observations $\left( x _ { 1 } y _ { 1 } \right) , \left( x _ { 2 } y _ { 2 } \right) , \ldots \ldots \ldots , \left( x _ { n } , y _ { n } \right)$ if large x's are paired with large y's and small x's are paired with small y's, then a __________ relationship between the variables is implied. Similarly, it is natural to speak of x and y having a __________ relationship if large x's are paired with small y's and small x's are paired with large y's.
