RE: Why is the term "non -significant" being used ?4 Oct 2022 17:56
As someone said below, the P-value is (I believe) an indication of the probability that the observed results occurred by chance.
By convention a P-value of 0.05 or less (a 5% chance it was a fluke, or 95% chance that it wasn't) is considered statistically significant. A P-value of 0.07 is considered to have too high a chance of having been achieved by fluke, and is therefore generally considered statistically insignificant.
It's quite a high bar.
As others have said, with the small trial numbers it's very difficult, the way the P-value is calculated, to get to statistical significance. P=0.07 is pretty close.
There is a slightly subtle but quite common misunderstanding of this subject which I may be guilty of, so if I'#m wrong about this I'm very happy to be corrected....
