Inaccessibility

I think the wording of the first paragraph is a good example of how Wikipedia is increasing inaccessible to the general public. How about:

In statistical hypothesis testing, a result has statistical significance if the probability that the observed results were due to chance is below a predetermined threshold known as the significance level. The significance level for a study is chosen before data collection, and is typically set to 5% or lower, depending on the field of study.

Comment on Dubious

The citation (USEPA December 1992) contains numerous statistical tests, some presented as p-values and some as confidence intervals. Figures 5-1 through 5-4 show some of the test statistics used in the citation. In two of the figures the statistics are for individual studies and can be assumed to be prospective. In the other two, the statistics are for pooled studies and can be assumed to be retrospective. Table 5-9 includes the results of the test of the hypothesis RR = 1 versus RR > 1 for individual studies and for pooled studies. In the cited report, no distinction between prospective tests and retrospective tests was made. This is a departure from the traditional scientific method, which makes a strict distinction between predictions of the future and explanations of the past. Gjsis (talk)
