What is what does significant mean?

Significant means that something is important or meaningful, often in the context of statistical analysis. It indicates that a result or finding is not likely to have occurred by chance, and that it has practical or theoretical implications. In statistics, a significant result is one where the observed difference between groups or variables is large enough to conclude that it is not due to random sampling error, but is instead attributable to some underlying factor or relationship. The level of significance is typically represented by a p-value, which indicates the probability of obtaining a result as extreme as the one observed, assuming that there is no real difference or relationship. A p-value of less than 0.05 is typically considered to be significant.
