Hello Friends,
This video is about learning all terms and concepts used in hypothesis testing.
We will learn Introduction, all terms and concepts in Hypothesis Testing with practical examples for easy understanding and better clarity.
This video consists of the following points:
• Why does a Hypothesis test comes into the picture with a practical example?
• Null and Alternative Hypotheses
• Two-sided and One-sided Alternative Hypotheses
• What are type I and type II errors?
• Example of type I and type II error
• Confidence Interval and Confidence Level
• What is a test statistic?
• What are the critical value and p-value?
I am sure you will be liked it.

Thank you so much for those valuable resources. Perfect speaking pace. Looking forward for normal and non-normal tests.

[sandeepmandrawadkar]

That's great and yet simple explanation on a very complicated issue. Hats off to you 👏

[navinchandraneolia]

the best video i went through for hypothesis concept.

[jayberdesigns]

Is 11:58 correct in saying P<ALpha ( .05) Fail to Reject the H0? Or is it P< ALpha(.05) Reject H0. Is the slide correct?

Super sir😎😎... Waiting for t-test, p-test, ANOVA, chi-square test with practical example using mini tab.!!

I need a hypothesis testing about 2 subjects score of public and private Scholl, grade 8..
1.one hypothesis is that there is no significant difference between the science subject at grade 8th in private and public school.
2.There is no significant difference between the student scores of math at grade 8th in public and private school..how I find the hypothesis testing??

[manoharnookala]

no body cant explain like this, great video i found

[geoschool]

Sir jo hypothesis testing ham krenge wo population distribution me hoga ia fir sample distribution me?

[v.c.jayaramaiah]

please provide elaborate and complete Lecture on Hypothesis testing

[abhishekchakrabarty]

I think it depends on the null hypothesis... Sometimes type 2 error can be more severe than type 1 and vice versa

[patibandladayana]

Thank you so much for the valuable resources

[anubhashrivastava]

Very well presented. Thank you
Will you please share links of videos that follow your this video.

[stex]

Thanks for sharing. I'm also very interested in the technique or software that are you using to realize that videos.

[mbaguru]

[HariHaran-hkfg]

Hi Bro, i want to know which software you are using for this session as i need to take paper presentation like u so pls help me bro

[chandcmu]

In medicine example, why type one error is less severe than type 2 error?

[axx]

excellent video, well explained. but please remove background music it is distracting

[albedokingofsun]

Are you sure that the p value and alpha relation is correct,

if p value is greater than or equal to alpha = we fail to reject Ho
if p value is lesser than alpha =we reject Ho
*THIS IS CRCT IG*
can u check it please

THANK YOU in ADVANCE

[safvaks]

Please add notes for psychological statistics

In the medicine example, i think type 1 error is more severe as if both medications are similarly effective, patients that do not want a very strong/effective medicine might buy any of them but have an undesirable result. It is relatable if you ever see someone eating only half of the panadol because they do not want the full effect of it.
