      @@statquest Hi Josh, great stuff, though I am still a bit confused. :) So that I can get the fact straight ... Question 1: "The threshold of 0.05 means if A and B are the same, there is only 5% of the tests will exhibit p-values that are less than 0.05". This statement is then equivalent to "If A and B are different, 95% of the tests will exhibit p-values that are great or equal than 0.05". If so, how can you come to a conclusion in the video at 8:48 that A and B are different just because they have ONE p-value which is less than 0.05? Question 2: When you say if some one wants to be very strict, he can set the threshold to be 0.0001. In this case, what will the corresponding p-value be, also 0.0001?

      ​@@jtbauer3789 Let me put this in a different way. Suppose that you are the guy trying to develop this new drug A. To be 100% sure that your drug really works and that isn't just luck or placebo that are curing people you would need to test this new drug in every person in the world, or even in the universe. For obvious reasons, this is not possible. To still be able to prove that your drug is curing people you can run this statistical test with a portion of people. We can say that this portion of people is a sample of your universe of people. For this statistical test, you need to establish a hypothesis that nullifies what you are actually trying to prove (this is the tricky part). In this case, this null hypothesis could be that your drug A is no different from drug B that we previously know that doesn't work. The origin of this knowledge about drug B it's not relevant for this test, you can just assume this previous knowledge. You also need to choose a threshold. Now comes the practical part of the test as explained in the video. You create two groups of people from your sample of people and each group is treated with only one of the drugs. You count, for each group, how many people got cured and how many were not cured. With these values, you calculate the p-value. The calculation of p-value needs an apart explanation. You just need to know that the p-value is the probability that the null hypothesis is true. Then if you get a p-value under the chosen threshold, this means a very low probability, it's very unlikely that the values that you observed in this one experiment happened only by luck (placebo or whatever). In conclusion, you can deny the null hypothesis and you can be pretty confident that your drug A does work.

      @@jtbauer3789 the equivalent statement should be that: if A and B are different, 95% of the the tests will exhibit p-values that are less than 0.05 since it will be more likely that the test will report significant differences thus producing smaller p-values most of the time. or if A and B are different, 5% of the tests will exhibit p-values that are greater or equal to 0.05(only 5% of the test should suggest that A and B are the same)

    Josh, this is really good! It covers that main points and helps us all focus on them. As a calibration person, I always find it interesting when I find situations in which we assume the perfection of the accuracy of our input data. This is not at all a criticism of your excellent effort, because if you tried to cover all considerations, you would never publish anything. This is what sank Charles Babbage. I appreciate how you pointed out the assumptions that are sometimes hidden in "hypothesis test". This is why juries find some people "not guilty" instead of "innocent".

      The problem with p values is that they are easy to manipulate and you need more information about an experiment than just the p value to assess if the results show anything.
      Let's say I have 100 drugs, test if they cure a diseases and say they are a good drug if the respective test resulted in a p value smaller than 0.01.
      Now even if no drug has any value we expect one p value smaller than 0.01, because we did so many tests.
      This happens a lot and instead a much smaller threshold should be used (e.g. by Bonferroni correction).

    Thank you so much! I'm a bit confused about why the closer a p-value is to 0, the more confidence we have that Drug A and B are different as if the threshold is 0.05 which means if A and B are same and if we did this exact same experiment a bunch of times, then only 5% of those experiments would result in the wrong decision. Then if the p-value is 0.03. It means only 3% of those experiments would result in the wrong decision. Why it doesn't mean it is more likely that A and B are same?

      The p-value tells us how different the observed data are from what we would expect if the data were the result of random chance. The smaller the p-value, the less likely that the data were the result of random chance.

      @OKUBO SELESTINE OPIYO It's not exactly "the the p-value, meaning there was less random chance influencing the results", it is more that "if it were random chance, then the event we saw would be very rare".

    If all the teachers were this fun and cleared concept with such lucid explanation, there would be many bright students who would be interested in the subject rather than cramming up definitions!

  • @qualitytoolbox4872

    In simple terms. I would say that “p values has the ability to identify rare events”. But before that you have to decide what a rare event would be. However. Explanation provided by Sir is awesome.

      emphasis on the "deciding before" part, as this is often overlooked in understanding p-values. 👍🏾
