WebDifference between means of paired samples (paired t test). When the effects of two alternative treatments or experiments are compared, for example in cross over trials, randomised trials in which randomisation is between matched pairs, or matched case control studies (see Chapter 13 ), it is sometimes possible to make comparisons in pairs. WebSince T will always be positive, the statement will be true if T is greater than 2.44 or less than -2.44. So, P ( T ≥ 2.44) = P (T ≥ 2.44 + T ≤ -2.44) = 0.24 and P (T ≥ 2.44) = 0.12. …
