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.

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

[rajaahlmohaamad]

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

[iainelder]

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!

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

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 .

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. ??

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

[snipershutze]

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

[herbertmandicheta]

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

[ijmusic]

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

[mohammedalali]

You are GREAT .. and well organized

thank you a lot ..

[sadmansakib]

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

[ladyashephd]

You made Quantitative methods much easier

[adriiguerra]

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

[tedtdu]

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

[ShivamSharma-tzew]

is this Matthew Mcconaughey behind the mic ?

[altamashkhan]

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

[MrHusseinhijazi]

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

[alaaahmed]

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