Inter- and Intra-Reliability Data

<p dir="ltr">The present study sought to assess and establish the reliability of a bespoke coding window to assess volleyball performance. This coding window was the first to combine a six-phase model of complexes along with efficacy scales that were individualised to each of the six key skills (Serve, Serve Receive, Set, Spike, Block, and Defence). The results of the study demonstrated Kappa and Weighted Kappa values above the acceptable thresholds for both inter- and intra-reliability, and that it was possible to utilise such a detailed system without the impact of Observer Drift.</p>
