Normative Comparison Standards for Measures of Cognition in the Canadian Longitudinal Study on Aging (CLSA): Does Applying Sample Weights Make a Difference?

Large-scale studies present the opportunity to create normative comparison standards relevant to populations. Sampling weights applied to the sample data facilitate extrapolation to the population of origin, but normative scores are often developed without the use of these sampling weights because the values derived from large samples are presumed to be precise estimates of the population parameter. The present article examines whether applying …
