 note = {The sender of a artial art expert pair attempted to send qi to the receiver in a sensory-shielded state under randomized and blind conditions. The receiver's electroencephalograms were treated by Fast Foureier Transform and used for  coherence function. Coherence function indicateds the correlation between measurements of brain waves obtained with two electrodes, Correlations of C3:C4, Fz:Pz and O1:O2 were examined. Some pairs of coherence function groups for different conditions were examined by the rank sum test and Welch's test. A statistically significant difference has been previously observed in the alpha wave amplitude betweem the sending and non-sending time zones by Welch's test. This alpha wave amplitude between two different time zones was rak sum tested. The probability that the O1:O2 coherence function group in the sending time and group in the resting time had the same distributiojn was under 5% by botyh rank sum and Welch's tests. The alpha wave amplitude at C4 was also 0.5% significant by the rank sum test. The practical conclusion is that the result by the rank sum test is similar that of Welch's test., Human PSI Forum},
