What you always wanted to know about the p-value, but were afraid to ask

A recording of the recent webinar, where Dr. Ulrich Dirnagl discussed the scientific ritual of significance testing.

Do you believe that the p-value gives you the probability that your result is a false positive? Have you ever contemplated the prior probabilities of the hypotheses you are investigating? Could you explain to anyone, including yourself, what statistical significance actually means? Do you know the “winner’s curse”?

In this webinar we tried to answer these and many other questions about the scientific ritual of significance testing, including whether we shall redefine, or even remove statistical significance, as many prominent statisticians and scientists have recently demanded.
