Sample text

66. Evidence on validity reported below shows that these pedometers were capable of revealing significant activity, subject, and subject-by-activity effects despite their limited reliability. That correlation coefficients are inappropriate for the determination of instrument reliability stems from the well-known fact that the correlation between two variables is zero when the variability in either X or Y approaches zero (cf. Chapter 1 regarding instrument reliability). If all pedometers yielded the same value, in either the test or retest conditions or both as is ideally desired, then the test-retest correlation coefficient would be zero!

Time-series analysis typically identifies the presence of autocorrelation, models it, and then removes it leaving properly uncorrelated points for subsequent traditional statistical analysis. Huitema (1985, 1986, 1988) has marshalled strong empirical support indicating that the distribution of autocorrelation coefficients within baseline and treatment conditions is centered about zero and ranges from strongly negative to strongly positive. This covers all possibilities. Repeated measurements can either be positively or negatively autocorrelated or they can be uncorrelated.

This demonstration is problematic in that limbs do not move in continuous circular orbits and that very low Ievels of acceleration were used. 4%. 0% indicating that actometers are responsive in two planes. 4%. 4-in. length is sufficiently short that it approximates the movement of the outstretched arm or leg. 155 which corresponds to error of 1ho to 117 of 1% corresponding to 99% reliability. Apparently the self-winding rotor revolved once each time the test device rotated once. Oscillating the same actometers in an unspecified manner for five additional 1-hr periods yielded coefficients of variation of 1.
