WebJan 1, 2024 · A statistically significant difference is simply one where the measurement system (including sample size, measurement scale, etc.) was capable of detecting a difference (with a defined level of reliability). Just because a difference is detectable, doesn’t make it important, or unlikely. READ ALSO: What is so special about goats? WebApr 14, 2024 · The mean MESA 10-year CHD risk with CAC was 7.8. There was a highly significant difference between the 3 groups (p < 0.001). The two IR groups did not differ statistically (p = 0.076). Survivors with IR including prediabetes have less frequent zero CAC scores than insulin-sensitive survivors.

WebMay 26, 2024 · This is highly statistically significant: the population correlation is very probably not 0.000... However, a 0.1 correlation is not distinguishable from 0 in a scatterplot. So it's probably not practically significant. Reversely, a 0.5 correlation with N = 10 has p ≈ 0.14 and hence is not statistically significant.
