Final answer:
Statistically significant refers to a result or finding that is unlikely to occur by chance. It is determined by comparing the observed data to a null hypothesis and calculating a p-value. If the p-value is smaller than a significance level, the result is considered statistically significant.
Step-by-step explanation:
Statistically significant refers to a result or finding that is unlikely to occur by chance. In statistics, it means that a hypothesis test has shown a difference or relationship between variables that is not likely due to random variation. This is usually determined by comparing the observed data to a null hypothesis and calculating a p-value. If the p-value is smaller than a predetermined significance level, typically 0.05, the result is considered statistically significant.
