MARTINEZ, JA. The consideration of the propagation of errors for the importance-performance analysis in sports management. CPD [online]. 2018, vol.18, n.3, pp.141-149.  Epub 26-Jul-2021. ISSN 1989-5879.

The importance-performance analysis (IPA) is a tool increasingly used in the management of sports services, but needs to be implemented from a more complete perspective when calculating and reporting measurement errors. In this research, we have provided precise indications to help to get that aim, through the calculation of the error bars and the propagation of errors for any function of the original variables: importance and performance. Through the simulation of several probability distributions, we have calculated the imprecision in the estimates, developing the Taylor approximation to compute the variance of a function of the original variables. The implications for sports research and management are finally discussed.

Palavras-chave : importance-perfomance analysis; sport management; errors propagation.
