Two one-sided test
WebJul 9, 2024 · The two one-sided t-tests procedure is operationally equivalent to the classical interval approach. That is, if the classical (1 – 2 x alpha) x100% confidence interval for difference or ratio is within LowerBound and UpperBound, then both the H 0 s given above for the two tests are also rejected at the alpha level by the two one-sided t-tests. WebJun 25, 2002 · When comparing statistical findings, the comparison should ideally be based on level of evidence. Thus, a two-sided symmetric 0.05 test has a greater level of evidence than a one-sided 0.05 test, but the same level of evidence as a one-sided 0.025 test that demonstrates the hypothesized beneficial outcome.
