AB - The statistical methods we have been discussing permit you to estimate the certainty of statements and precision of measurements that are common in the biomedical sciences and clinical practice about a population after observing a random sample of its members. To use statistical procedures correctly one needs to use a procedure that is appropriate for the study design and the scale (i.e., interval, nominal, ordinal or survival) used to record the data. All these procedures have, at their base, the assumption that the samples were selected at random from the populations of interest. If the study as conducted does not satisfy this randomization assumption, the resulting P values and confidence intervals are meaningless.
