Hypothesis Testing 02: 10 Steps

Yes, 10 steps does seem like a lot but there's a reason for each one, to make sure you consciously make a decision along the way. Some of the steps are very quick and easy. I've seen other books condense this to 7 or 5 steps, but ultimately it's the same process. Choose what works for you.
Again, my reference is an old Biostatistics book I used in 2005, the 8th edition by Daniel.

This is the first explanation I've seen that explains why you should work out the p'value even if you already base your decision on the test statistic. "We were gonna accept it regardless, but maybe it was even better than that!" Your explanation is ethusiastic and your graphics are vibrant. Thanks!

Thank you for your kind words!

What is the meaning of the z's and the t's??

[@AnaheimElectronicsInc.]

z is for samples that are greater or equal than 30 or normally distributed, t is for sample size smaller than 30

[@marianaumbria1411]

It does not matter that is long. You got all the elements need to do the hypothesis testing perfectly. Thank you

[@rajaahlmohaamad4906]

Excellent explanation in a short and simple way. Thank you so much. A lot of confusion solved right after watching this video.

[@davikaacademy4264]

This is the reason I have started my channel here to help others understand mathematics like you. This is very good approach in this field ,DAVIKA Academy which is my channel am working on both pure, applied and statistical mathematics. Once more keep it up let us transform the educational sector .

[@Inflationmaker]

THIS EXPLANATION WAS REALLY REALLY GREAT ! EASY TO UNDERSTAND. THANKS ALOT EVERY TIME I SEE YOUR VIDIOS.

[@deewastamang9135]

Thank you sir! You're a saviour.

[@JohnSmith-yy5zp]

Sampling is your step 1. What are your data takers looking for when you don't do your alternate hypothesis until step 3? I'd think you want to make your prediction first, and then send your crew out to sample to support that prediction. ??

[@saleemghani5443]

pls explain,use of Z and T test when n less then 30

A manufacturer of a certain type of auto batteries claims that the mean life of his batteries is 45 months. A consumer protection agency that wants to check the claim took a random sample 36 such batteries and found that the mean life for the sample is 43.75 months, with a standard deviation of 4 months. a) Using the 2.5% significance level, would you conclude that the mean life of the batteries is less 45 months b) Using the 5% significance level, would you conclude that the mean life of the batteries is less 45 months

[@emilrajan7995]

a) At 2.5% level of significance, we fail to reject Ho:Popl Mean =45, since Tcalculated > Tcritical. b) At 5% level of significance we reject Ho:Popl Mean =45, since Tcal

[@snipershutze]

Excellent explanation! I thing statistics are hard to undertand but if whe keep in a simple line it´s make sense

[@ijmusic7302]

where from collect the and how can test the hypothesis and test that ?

[@sadmansakib5477]

Your presentation is actually pretty good :) keep up the good works

[@herbertmandicheta]

thanks a lot, its now clear. You are the best

[@adriiguerra5289]

where can I find an article that I can test ?:)

[@mohammedalali8801]

You are GREAT .. and well organized thank you a lot ..

[@ShivamSharma-tz3ew]

is this Matthew Mcconaughey behind the mic ?

[@ladyashephd727]

You made Quantitative methods much easier

[@tedtdu]

5th and 8th seem to same to me. you do not have to have 10. Why not just 6 steps.

[@balqeskrikish2809]

That’s really helpful thanks 🙏🏻

[@MrHusseinhijazi]

thx and good job.. nice and easy. makes more sense now. (y)

[@emreyilmaz8349]

Well Played !

[@YBthatGuy]

Very clear explanation! Thank you

[@territan1234]

Amazing

[@TheFlyrodder68]

Good stuff. Thumbs up!

[@altamashkhan1052]

please solve this anyone Suppose 300 misprints are dsitributed randomly throughout a book of 500 pages . find probability that a given page contains (a) exactly 2 misprints (b)2 or more misprints

[@sinfall5280]

Do you still need it?

[@jennicevelasquezrealtor2279]

Not accept but fail to reject

[@shegawabate333]

realy helpful .contiue...

[@anumariasunny5971]

Thankyou

[@bndkgr]

Nice viddy man! Thanks alot :)

[@ajmalhaidari7140]

Thanks alot Patwari

[@akhilsourav3070]

Good ❤️

[@alaaahmed7662]

by the way our claim is ha and we should test it ,

[@jassisandhu7569]

M power 4 and n power 3

[@charlesdaka4724]

thankx alot. this video really helped

[@lesleydhlagwayi9605]

it was really helpfuul

[@abhinavkulshrestha5271]

9:35 loooool xD

[@rohan2609]

good video, but it felt as if you forced in a few steps to get 10, but then thank you.

[@anjansaraswathibatla1657]

thankx alot. this video really helped
