Important Resources for Statistically Significant:
There is 1 user following this page.
When groups of patients are studied in clinical research, there will always be differences between the groups. These differences may be large or small, quantity or quality, simple or complex. Most importantly, it may be:
- real, actual, true differences
- simple, random, chance fluctuations
Clinicians need to know if clinical studies lead to true differences in treatments.
To distinguish between these two possibilities, statisticians model random chance fluctuations using mathematical models, and assess the degree to which observed differences could be due to chance alone.
If the results show the group differences to be unlikely to be due to chance alone, then the differences are deemed statistically significant.
