  • Understanding Measurement: Aspects of Reproducibility and Validity

    Distinguishing reproducibility from validity; how reproducibility influences validity; methods of characterizing reproducibility of measurements (within-subject standard deviation, intraclass correlation coefficient, coefficient of variation); methods of assessment of validity in the presence and absence of gold standards
