NCIt definition : In statistics, a number that expresses the probability that the result of a given
experiment or study could have occurred purely by chance. This number can be a margin
of error or it can indicate a confidence level.;
Alternative definition : CDISC-GLOSS: The likelihood that an event occurs by chance (e.g., the null hypothesis
is rejected). NOTE: For example, one may say significant at the 5% level, which is
usually represented as p 0.05. This implies that there is a 95% probability that
the effect did not occur by chance. [After AMA Manual of Style; After Principles of
Epidemiology in Public Health Practice, Third Edition, An Introduction to Applied
Epidemiology and Biostatistics, Oct 2006, Updated May 2012, US DHHS]; NCI-GLOSS: Describes a mathematical measure of difference between groups. The difference
is said to be statistically significant if it is greater than what might be expected
to happen by chance alone.; MRCT-Ctr: Results that are very unlikely to have occurred by chance. (https://mrctcenter.org/glossaryterm/statistically-significant/);
