Difference between the mean values of the WFs for the four shortest and four longest ICIs proved to be highly significant [ t (9) = 7.21, p < 0.0005].
Difference between the mean values of the WFs for the four shortest and four longest ICIs proved to be highly significant [ t (9) = 7.21, p < 0.0005].
Cumulative probability of having this ratio (eight or more out of 10) by chance was calculated to be p = 0.0547, which is very close to significance at α = 0.05.
