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.

Agility Test Innovation on Special Badminton Athletes for the Junior Category (U17): Validity and Reliability

“…The results of the validity of this test were supported by nine experts from academics in the badminton field and nationally licensed trainers who stated that they supported the six aspects of Y agility test. Then the results of the reliability test using Cronbach's Alpha 0.817 and Interclass Correlation Coefficient 0.818 that these results have a high level of reliability, reinforced from the results of previous studies that are similar to Nugroho and Utama, that the values of Cronbach's Alpha and Interclass Correlation Coefficient above 0.8 can be concluded to have a good level of reliability (W. ; (Utama et al, 2023). In this reliability test, in order to obtain high reliability results, the involvement of 55 badminton athletes aged 15-17 years is needed.…”
