3.3.1 Standard Error of Measurement
The SEMs for the STP (baseline-to-peak) approach ranged from M = .44 (SD = .095) to M = .68 (SD = .132), with more variability shown in the later components (see Table 9). The STW approach ranged between M = .43 (SD = .094) and M = .55 (SD = .117). Pearson’s correlations between the STP and the STW approaches yielded very strong values at or above r = .93. These data indicate that the SEMs were comparable for the STP and STW approaches across participants.
