Finally, the MTI instruments on average needed significantly less (9.95%) acceleration to produce one thousand counts per minute when comparing the acceleration responses in the group of MTI and CSA units across all settings and time points (Table 6).
When compared to the CSA units the MTI instruments, on average, needed significantly (p < 0.001) less acceleration in order to produce 1000 counts*min-1 To our knowledge, no other study has examined and compared the effect of calibration on inter-instrument reliability after applying unit-specific calibration factors to data obtained both in the laboratory and in the field.
In this table, the different metrics are given per instrument on average for the ten excerpts in the test database.
Not surprisingly, the novice tester was the slowest on both instruments, taking on average, five minutes per guideline (range 3 7 minutes) with the iCAHE instrument, and up to 20 minutes per guideline using the AGREE II instrument (average 18 minutes (15 20 minutes range)).
Scores pertaining to stigma as captured by the PROQOL instrument were lower, on average, than all other domains and notable for lack of significant association with any of the clinical factors considered.
We also found that, on average, instruments in the NCG-study slightly underestimated both weight (mean: –0.14 kg) and height (mean: –0.07 cm) measurements.
The estimated prevalence was 16.4% with no instrument error and was, on average, overestimated by 0.5 percentage points based on observed variance of instrument error from the NCG-study.
As expected with the increased read lengths from the 454 GS XLR70 Titanium instrument, our contigs were on average larger (mean = 500 bp) than those assembled in previous studies that used earlier 454 technologies with shorter reads (e.g., 197 bp, [ 5]; 247 bp, [ 7]; 440 bp, [ 16]).
On average, the instruments onboard consume between 2 and 10 watts — about the power of a night light — when turned on.
Thus, adding at least twice as many items (the shortest additional Big Five instruments has 10 items) resulted on average in a duplication of the explained variance.
The proportion of variance explained clearly varied as a function of the length of the second Big Five instrument: Instruments with 10 or 11 items explained on average an additional 10% of the total variance explained by personality.
