Paired t-Test -- from Wolfram MathWorld - Wolfram MathWorld: The Web's Most Extensive Mathematics Re Given two paired sets X_i and Y_i of n measured values, the paired t-test determines whether they differ from each other in a significant way under the assumptions that the paired differences are independent and identically normally distributed. To apply
