Performance norms for British National Super League Netball

Abstract

The use of norms allows performance indicator values to be related to the relevant population of performances. However, it is also necessary to relate performances to the quality of the opposition. The purpose of the current investigation was to determine percentiles for performance indicators in British National Super League netball. Percentiles were determined for different types of match based on the strengths of the teams involved. The strength of the opponent was found to effect teams in the top half of the league differently to teams in the bottom half of the league. Relating a team's performance to the relevant performance norms based on the strength of the opposition permits more effective interpretation of the performance indicators. This information can be used by coaches to identify facets of performance requiring attention and can support more effective decision making and use of video feedback.
