A separation of simply one standard error of the difference would only fail me 68% confidence that the two scores are different. As a issuance of the workings below I can be, 95% confident that the two scores (verbal comprehension) and (perceptual reasoning) differing by 2?diff (10.8) represent truthful score differences. Table 2. modes of calculating the st! andard error of difference between two scores: Method one: Method two: ?diff=... If you want to make for a full essay, gild it on our website: OrderEssay.net
