Significance
Significance refers to the importance, relevance, or meaning of something, particularly in the context of statistics, where it denotes the probability that an observed result, such as a difference between two measurements, is caused by something other than random chance.
Statistical Significance[edit | edit source]
In statistics, significance is a measure of the probability that an observed difference in data is not due to random chance. This is often measured with a p-value, which represents the probability that the observed data (or data more extreme) could occur if the null hypothesis of no effect is true. If the p-value is below a certain threshold (often 0.05), the result is said to be statistically significant.
Philosophical Significance[edit | edit source]
In philosophy, significance can refer to the meaning or importance of a concept, argument, or discovery. This can be subjective and dependent on one's perspective or framework of understanding.
Clinical Significance[edit | edit source]
In medicine and psychology, clinical significance refers to the practical importance of a treatment effect—whether it has a real genuine, palpable, noticeable effect on daily life.
