Title: How significant is significance? What do p-values really tell us?

It is our duty to ensure that the evidence generated by the research we undertake is interpreted in the best way possible in order to provide the best outcomes for our patients and the general public. P-values and the concept of statistical significance are central to this. In this talk, I will present a (very!) brief history of statistics to explain why the concept of p-values has been taught the way it has, why this might not be quite right and what we might be able to do about it.
