Validity and Reliability of Table Tennis Performance Measuring Eye-Hand Coordination

Abstract

The ability of eye-hand coordination is needed in table tennis performance. Therefore, measuring the eye-hand coordination of table tennis performance is necessary. This study aimed to develop a measuring instrument for table tennis eye coordination and test its validity and reliability. This study uses mixed methods - data collection using the Delphi technique and test-retest. The participants were three academic experts, four table tennis professional experts, and fourteen table tennis athletes. This research instrument uses a questionnaire with a rating scale of one to four, namely very relevant, relevant, less relevant, and irrelevant. It uses a measuring instrument for hand-eye coordination. Data analysis used Aiken's formula, Intraclass Correlation Coefficients (ICC), and Cronbach Alpha. The results of this study that measuring eye-hand coordination of table tennis performance show the first aspect: the suitability of the coordination concept has a value of V = 0.952, the second aspect: the suitability of the number of stimuli has a value of V = 0.857, the third aspect: the suitability of distance has a value of V = 0.952, the fourth aspect: the suitability of the movement has a value of V = 0.857, the fifth aspect: the suitability of the test procedure has a value of V = 0.857. The Intraclass Correlation Coefficients (ICC) test has a value of 0.875. The reliability test has a value of 0.891. Based on these results, the eye-hand coordination measuring instrument has content validity and high reliability. Therefore, the eye-hand coordination measuring instrument can be used to measure table tennis performance.
