Abstract

This study aimed to find out the level of validity and reliability of groundstroke skill test in tennis. This study was conducted to beginner and advanced tennis athletes in West Sumatera. The study population was all tennis athletes in West Sumatera. The sampling technique was random sampling technique in which the population was sampled by 34 respondents. The data were collected through tennis groundstroke skill test. The retest of Hewitt tennis groundstroke test was performed by calculating the scores. The validity test of tennis groundstroke skill was sought by correlating the result of tennis groundstroke skill test to the result of Hewitt groundstroke test. Meanwhile, the reliability test of tennis groundstroke skill was sought by correlating the result of tennis groundstroke skill test to the result of retest of tennis groundstroke skill test. Based on the analysis of data, for the group of advanced athletes, the level of validity of tennis groundstroke skill test was 0.86 which means good, while the level of reliability of tennis groundstroke skill test was 0.76 which means that it could be accepted. Then, for the group of beginner athletes, the level of validity of tennis groundstroke skill test was 0.30 which means low, while the level of reliability of tennis groundstroke skill test was 0.20 which means that it could not be accepted, so tennis groundstroke skill test was more suitable for the group of advanced tennis athletes.
