Estimated effect sizes, measurement variability, and correlations between baseline and follow-up measures were estimated using unpublished datasets from studies of physiologic measures in adult and pediatric populations.
Second, scholars accept findings of no significance as evidence of no relationship (Weisburd et al. 2003), not always recognizing possible problems related to sample sizes, measurement error, or other features of research design.
However, these studies were limited by small sample sizes, measurement of the complex VOC mixture in terms of the total concentration, and presumption of personal exposure based on the identification of emission related-material or the human activities [11].
Unless cuffs inflate in a specific way to ensure that the proper functional cuff size is used for patients with various arm sizes, measurement accuracy can be affected.
Studies also have been limited by small sample sizes, measurement approaches that used manual delineation of the hippocampus/amygdala, or whole brain voxel-based morphometry methods sensitive to registration and partial volume confounds.
Besides, even in doing science, scientists are forced to make hundreds of value-laden, methodological judgments, about everything from proper sample sizes, measurement errors, and possible model biases, to data interpretations [ 34].
