Document Summary

Week 10 (lecture 1) measurement: issues in quantifying individual responses to exercise. Positivism we can objectively measure the truth in objects. We know the truth through objective measures. Within paradigm giving of a numerical value to a phenomenon. Ability to measure and quantify = central to science. Continuous can assume any reasonable value (2 sig. digits), interval scales (values are evenly spaced), ratio scales (have meaningful 0 value) Categorical (nominal variables) have named categories, 2 conditions = categories are (cid:373)utuall(cid:455) e(cid:454)(cid:272)lusi(cid:448)e, are (cid:272)olle(cid:272)ti(cid:448)el(cid:455) e(cid:454)hausti(cid:448)e (cid:894)does(cid:374)"t fit i(cid:374)to a(cid:374)(cid:455)(cid:895) Discrete (ordinal scale) points of a scale can fall along a continuum but distance between points not constant, constrained to a whole number or value. Some phenomena easy to quantify and assign a numerical value to = directly observable, can be objectively measured.
