WebJan 9, 2024 · Mathematically, P-value and CI show two aspects of the same thing.

It becomes 1 when values of both groups are same(identical). Here, r= 1. Actually, when p value approaches near to 1 eg 0.99 or .98 it is regarded as 1.

WebP values and confidence intervals are intertwined. If the P value is less than 0.05, then the 95% confidence interval cannot contain the value that defines the null hypothesis. (You can make a similar rule for P values < 0.01 and 99% confidence intervals, etc.)
