What is Statistical Significance? Definition and meaning

Statistical Significance

Definition: Statistical Significance is the likelihood that a relationship between two or more variables we find in our results is NOT caused by random chance.
In any experiment or observation that involves drawing a sample from a larger total population, there is always the possibility that an observed effect occurred due to sampling error (coincidence). Statistical significance is a way of showing to what extent that the answers which were obtained from the data are not totally due to luck.
