... o The smaller is, the less likely that is rejected. A very small may be necessary if rejecting is a costly decision, or if is an established theory. o In practice, always report the P‐value. What’s the difference between 0.049 and 0.051? Statistical significance is not the same t ...

... • Experiment - The process by which an observation is noted and consists of one or more trials. • Event – A subset of all the possible outcomes of an experiment E.g. Rolling a 6. • Sample space – The set of all feasible outcomes of an experiment. E.g. when rolling a die the sample space is: (1, 2, 3 ...

The null hypothesis, commonly denoted as H0, is the hypothesis of interest; whereas the alternative hypothesis, HA, is the complement of the null. Properly stated null and alternative hypothesis cover all alter ...
