A Researcher Wishes to Estimate the Reliability of the FYI

question 37

Short Answer

A researcher wishes to estimate the reliability of the FYI (Functional Youth Indicator) - a new test of adolescent shyness. The test is composed of a total of 30 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 teen-age males was randomly selected and their scores were as follows: $$\begin{array} { l c r } & \text { Odd } & \text { Even } \\\text { Subject \# } & \mathrm { X } & \mathrm { Y } \\\text { 1. } & 10 & 9 \\\text { 2. } & 8 & 11 \\3 . & 12 & 12 \\\text { 4. } & 10 & 9 \\\text { 5. } & 11 & 10 \\\text { 6. } & 9 & 10 \\\text { 7. } & 10 & 9 \\\text { 8. } & 15 & 14 \\9 . & 5 & 6 \\10 . & 10 & 10\end{array}$$ Estimate the reliability of the whole test.
