What is p-value? How we decide on our confidence level.

Understanding the definition of p-value guides us in setting the level of confidence we want, which in turn gives us alpha - the significance level. Check out "Why we say Fail to Reject the Null" • Why do we say Fail to ...

    Everything went smooth except how can a coin be heads on both sides? unless it was a prop coin just for this experiment, only the can a value for p begin but logically if one knows its a regular coin it nulls the experiment.I guess the assumption of a fair coin is what gives it existential value it is also true with life.

    the part that still bothers me is that i equate the confidence level with the null hypothesis; like i am confident that the null is true. However, in the video the dude says "i am 97% confident the coin is not fair" which goes against the null hypothesis. So do I just have this backwards and the confidence level trying to prove the null is incorrect?

  • @TheStatsFilesDawnWrightPhD

    Actually, the confidence level is about not making a mistake in rejecting the null, e.g. we want only a 5% chance of rejecting a true null, loosely speaking.
