Abstract
This article presents the second part of the results of the project, which was implemented in 2011 in cooperation with the Light Aircraft Association (LAA CR hereafter). The aim of this project was to analyze the properties of test from the theory of paragliding.
This test from the theory of paragliding is part of the examination for obtaining a pilot's license in the LAA CR, and therefore it was necessary to assess the quality of this diagnostic tool. In this second part, we analyzed the quality of distractors, we assessed the validity and reliability of the test and we dealt with unusual situations that may arise in calculating the sensitivity of the task.
Of the total number of 584 distractors we found 8% distractors as unsatisfactory and we recommended to replace them. When assessing the content validity, 3 of 292 tasks were designated as unsatisfactory.
After removal of these tasks the test will be sufficiently content valid. The result of the estimation of reliability by method of Kuder-Richardson, which we modified, was 0.8, and we consider this a satisfactory reliability.
Based on comparing three coefficients of sensitivity biserial coefficient is considered the most suitable.
