Hi there, I'm completing a research class in my NP curriculum and you've pretty much summed up 3 chapters in a nicely explained 16 min. video. Honestly, statistics is such an abstract topic, but you've managed to clearly explain and correlate concepts in a very logical and understandable way. I will be referencing your video in some of my discussion boards. Thanks for taking the time to put this together. Great job!

One thing that I would point out is that a p > 0.05 DOES NOT mean that there is "no statistically significant difference" (see 10:09). It only means that we cannot tell if there is a statistically significant difference.
@reconshunter
@reconshunter Жыл бұрын
I still have issues understanding the p-value. If it is, as you said 7:02 then having a high p-value, therefore a high probability that we will again get a difference of 20 between the two groups, would that no indicate, that there is a difference and therefore the groups are not the same? Why does a low probability for a difference indicates that they're not the same?

It is true scientists have a personal bias for their alternative hypotheses. But, one of my professors taught me an important lesson when examining results. That is, even if we don't end up having enough evidence to reject the null, we still learn something. "The truth is always more interesting than the hypothesis," he said.
