It is important to have an understanding of statistical significance. What does statistically significant mean?
Statistically Significant Definition:
A result in a study can be viewed as statistically significant if the probability of achieving the result or a result more extreme by chance alone is less than . 05.
It is important to understand that statistical significance reflects the chance probability, not the magnitude or effect size of a difference or result. A result could be statistically significant and the difference between two groups could be very small. Also, a difference between two groups could be large but the difference fails to be statistically significant (the chance probability is greater than . 05).
