   Significance
   Results of an experiment are said to be statistically significant when they are very unlikely to be due to chance (and hence, in a psi test, are more likely to be due to psi). The chance probability is reported as the `significance level`. To be considered significant, the chance probability must generally be less than 1 in 20 (5%, or 0.05).

   Significance
   Significance is an English word that has been hijacked by statisticians. In general usage the term significant difference means an important difference, but 'significant' in this sense is subjective. On the other hand, statistical significance is objective, and is based on the concept 'p<0.05'. In an experiment, a difference is detected by challenging a null hypothesis of 'no difference'. When p is less than 0.05, the null hypothesis is rejected - when p is greater than 0.05, the null hypothesis is accepted. So what does p<0.05 really mean? A p value of less than 0.05 means that there is even less than a 0.05 probability of getting the observed test statistic if the null hypothesis is true. This is an incredibly misunderstood concept, by even experienced users of statistics. See also Probability.

    significance
    A finding in economics may be said to be of economic significance (or substantive significance) if it shows a theory to be useful or not useful, or if has implications for scientific interpretation or policy practice (McCloskey and Ziliak, 1996). Statistical significance is property of the probability that a given finding was produced by a stated m...
