EXTRACHANCE

is an adjective used to describe a set of test results which differ greatly from the expectations planned before the (psychology) experiment was conducted. This phenomenon is specifically associated with para-psychological experiments.

EXTRACHANCE: "Experimental results do not always follow their predicted values, extrachance occurs when the divergence between predicted and actual is large."
