Predictive validity refers to the extent to which a test or measurement accurately forecasts or predicts outcomes based on the data collected. It is a crucial aspect of evaluating the effectiveness of assessment tools, particularly in ensuring that the imputed data reliably reflects future results or behaviors. In the context of imputation methods, predictive validity helps determine how well the values substituted for missing data points can anticipate actual outcomes, which is vital for maintaining the integrity and reliability of research findings.
