Short Answer

A researcher wishes to estimate the reliability of the new test of a person's sense of humor, the LOL test (Lambda Orientation Level). The test is composed of a total of 40 items, and the researcher splits the scoring in order to compare each subject's score on the odd numbered items with those on the even numbered items. A total of 10 adult males was randomly selected and their scores were as follows: $$\begin{array}{l}\quad\quad\quad\quad\quad\text { Odd}\quad\text { Even }\\ \begin{array} { l c c } \text { Subject \# } & \mathrm { X } & \mathrm { Y } \\1 & 15 & 17 \\2 . & 10 & 13 \\\text { 3. } & 5 & 8 \\\text { 4. } & 8 & 8 \\\text { 5. } & 12 & 12 \\\text { 6. } & 13 & 13 \\\text { 7. } & 7 & 10 \\8 . & 10 & 8 \\9 . & 11 & 12 \\10 . & 9 & 9\end{array}\end{array}$$ Estimate the reliability of the whole test.
