How To Identify Type I and Type II Errors In Statistics

This statistics video tutorial provides a basic introduction into Type I errors and Type II errors. A type I error occurs when a true null hypothesis is rejected. A type II error occurs when a false null hypothesis is not rejected. This video contains a few examples and practice problems of how to identify these errors.

why do college professor take hours explaining these things while this guy does it better in 10 minutes?

[@mrnobody22194]

Many of these professors don't have a degree in public education/teaching background despite their long life experience, i admit it my professor literally can't even explain it articulately so don't expect much imho.. just go to college, sit, do some assignments, and mid terms then final exams, or quizzes, pack ur shit and graduate.

[@eesaarashid1954]

So, when it comes to which type error has greater consequence it always depends on the context. In addition, as long as you justify it.
For examples for the last example I believe type 2 error is greater consequence as the defendant could be a murder. Therefore, a high risk chance of somebody being murdered. That's my opinion and you can argue with it the other way round

Wonderful explanation. Identifying the bad decisions first and then see where NULL hypothesis is rejected, will lead to find TYPE I error. Wow. You nailed it. (Y)

[@ArsArcanum]

[@DA-uz8qb]

The terminology around the decision to reject or not reject the null hypothesis is awkward, but it has a reason for being so. When testing hypotheses, one cannot accept the null hypothesis; one can only reject it, or not reject it. Since we cannot take action to accept the null hypothesis, we are left framing it in terms of rejection (reject null hypothesis, not reject null hypothesis). It would be much easier to say "reject" or "accept" rather than "reject" or "not reject", but it is only accurate to frame it in the latter way.

[@omerutkuerzengin3061]

P(Fail to reject Ho| Ho False) = Type II error.
P(Fail to Accept Ho| Ho True) = Type I error.
Type II error is the probability of a decision.
Probability is a result of any action or experiment.
Type I and Type II error are the result (probability).
What you have written in this table is equal to the Probability of Probability Conditional.

[@irinabartnik5306]

Correct me if i am wrong, but Type 1 or Alfa error has a greater significant, therefore your first example was set up wrong . Ho should have said "Johns used car is NOT safe to drive " that would make first rejection type1 or more significant ... Right?

I'm same with you at first but after saw again that's I was wrong😅

[@DA-uz8qb]

In terms of consequence and rules of evidence, extraordinary claims (hypotheses) require extraordinary evidence to support their validity. The null hypothesis is always assumed to be true as a baseline --- it is the status quo. In order to overturn or reject the null hypothesis, one needs to bring extraordinary evidence. In terms of the law, the assumption is always innocence until extraordinary evidence is brought forth to overturn the assumption of innocence. This bias is to help ensure that the bigger consequence (innocent man is deemed not innocent) is less likely to occur than the smaller consequence (not innocent man is deemed innocent). This law favors individual protection from the immensely powerful legal system, in favor of a more distributed risk to society of having a not innocent man roaming free.

[@Lilly10-x4w]

I think in the last example type II error haa greater consequences because when the defendant is guilty and is free he would do more crimes and might hurt more than 1 person but type I, just one person is hurt

[@esadakcakus3126]

putting an innocent soul under a punishment is way worse than undoing all the punishments for bad souls

[@Suyaang]

[@bonky8043]

Never make the type 2 error of choosing a False Ho 😂
Or the type 1 error of rejecting a True Ho 😢

[@tulam5473]

I think C) Type 2 error would lead to greater consequences because the person who is not innocent is accepted as not guilty would lead to not imprisoning them and they are free to commit crimes that will cost many other people whereas if A) the innocent person is accepted as guilty and goes to prison it is a bad decision but it only costs that one person.
I think contrary to the video C Type 2 error would cost more lives and thus have greater consequences!

[@Aku_lo.li9]

Love you ❤

[@parthmaheshwari1705]

1 innocent should not be punished even if 100 guilty escape away.

[@eitanyisraeli2401]

Question 2 part C is pretty much a moral debate. Obviously an innocent man in jail is horrible but what if the guy who was let off the hook now goes and commits a school shooting? You can't actually say one is worse than the other.

[@LAKSHAYANAND-k8k]

In the last Question, why don't you tell what the actual answer would be (Textbooks & Exams) rather than telling from your point of view ...It is the type 2 error which should have greater consequences... Because a guilty man would do more crimes if not punished

[@englishlife5838]

Honestly for the last own, if we are thinking logically, statement C should have a greater consequence because having a not innocent guy with the judge thinks he is not guilty causes more trouble than the other way around. Think about this, if that man is a killer, he would kill more people and you would lose more lives. But, if you place an innocent person in prison, you would not lose any lives.

[@Abaddon-u1i]

[@Phyziks_Enlightenment_]

In second one it may possible that the man who is no innocent and however get free due to wrong decisions then he can probably cause a great harm to community so i guess it has greater consequences
