Probability & Statistics/P value


Dear Clyde Oliver,

I have one question please.
I conducted the t test and got p value.
Does high p value mean that 2 testing variables are more identical? I tried several models/methods and need to choose one. But I need to choose models where 2 variables are more identical. In that case can I rely on the highest p value?
Thanks in advance.



No, it does not. The "p" value indicates the probability that the phenomenon you are testing occurred due to random chance.

Unless your p value is very small (less than 0.05), you would not normally say there is any statistically significant phenomenon in your data.
