Statistically significant means that the probability of obtaining the observed results by chance is very low, typically less than 5% (p<0.05). This indicates that the results are likely to be a true reflection of the population being studied, rather than simply a result of random variation or sampling error. Practical significance refers to the importance or relevance of the results in the real world, while substantive significance refers to the magnitude or size of the effect. Theoretical significance refers to the implications of the results for existing theories or models.
