Common sense and NHST
Naive common sense sometimes doesn´t work To deal smoothly with random events is an entire timelife endeavor, and it is, doubtless, the hardest part to perceive in order to be pretty comfortable, if so, with Data Processing, I mean. Let be the ?counter sense?, but although true situation: It can happens that two nosignificant pvalues, issued from two independent NHST´s tests, can consist in a highly significant over all result. Common sense says contrarily; if I found a nosignificant value, and a second time too, common sense says that I got a strengthen evidence not to reject the null. NOT NECESSARILY, of course as we will show soon.
