Essay

Suppose a small group of expert physicists and mathematicians held a joint conference. You, being an opportunistic sort, talked them all into taking two personality tests. The first test measured the need for achievement (N-Ach) and the second measured the need for affiliation (N-Aff), which is a desire for association with other people. Below are the scores. What conclusions can you reach about the relationship between need for achievement and need for affiliation among these scientists? $$\begin{array} { l c c } \text { Person } & \begin{array} { c } X \\\text { N-Ach }\end{array} & \begin{array} { c } Y \\\text { N-Aff }\end{array} \\\hline 1 & 28 & 12 \\2 & 27 & 10 \\3 & 25 & 14 \\4 & 24 & 18 \\5 & 24 & 11 \\6 & 23 & 15 \\7 & 23 & 16 \\8 & 23 & 19 \\9 & 22 & 22 \\10 & 21 & 20 \\11 & 19 & 18 \\12 & 18 & 24 \\13 & 17 & 25 \\14 & 15 & 23 \\15 & 13 & 26\end{array}$$
