WebFeb 16, 2024 · Significance is usually denoted by a p-value, or probability value. Statistical significance is arbitrary – it depends on the threshold, or alpha value, chosen by the researcher. The most common threshold is p < 0.05, which means that the data is likely to occur less than 5% of the time under the null hypothesis. WebCQCONF () —Calculated confidence in the C q value is low.
