Document Summary
Lecture 3 methods of assessment: cross-sectional studies = individuals are measured or observed at a given age, or individuals of several ages are measured (single time point, not overtime). Longitudinal studies = repeated observations on the same individual at specific intervals over time. Information gathered at multiple time points (i. e. , growth and development). Longitudinal studies are especially useful from 0-3y and through adolescence because these are periods of much growth. Interval = ordered units with the same difference between them (ex: temperatures: ratio = ordered units with the same difference between them and absolute 0 (ex: height, the practice of making observations is not inherent. Observations may be objective or subjective: ex: noticing the difference between kids and adults running adults have more consistent structure and a more distinct knee drive. Lecture 4 somatic growth: can measure body size through mass, stature (floor to vertex of skull), recumbent length (lying length, recumbent length is greater.
