Notes:
All values represented as mean (SE) collapsed for pain
*
significant difference based on the main effect of speed (p<.016)
A
approaching significance based on the main effect of speed (p<0.05)
Mean= traditional “mean” performance variable
SD= within subject standard deviation (σ)
CV= Coefficient of Variation expressed as % (σ/μ * 100)
