... I Can you really draw directional conclusions when all you did was reject a non-directional null hypothesis? Yes. Decompose the two-sided size α test into two one-sided tests of size α/2. This approach works in general. It is very important to state directional conclusions, and state them clearly in ...

... is called the prior distribution. In a Bayesian statistical analysis, each parameter requires a prior distribution. Consequently, you will have multiple prior distributions in multi-parameter situations. Because a prior distribution can be selected arbitrarily, this term of the Bayesian approach is ...

... Reasoning • As with confidence intervals, we ask what would happen if we repeated the sample or experiment many times • Let X ≡ weight gain – Assume population standard deviation σ = 1 – Take an SRS of n = 10, – SExbar = 1 / √10 = 0.316 – Ask: Has there weight gain in the population? Basic Biostat ...
