Sir mujhe first question mein ye samjh nahi aaya ki aapne los (alpha) ko half kyu kiya...hume kaise pta chala ki ye two tail value hai ya nahi aur last mein answer aaya tab sigma 1=sigma 2 hi toh aaya iska mtlb vo twotail value nahi hai....kab alpha ko half karna hai kab nahi samjh nahi aaya please explain kijiye please reply sir 🙏🙏
Understood the concept 😊👍 Sir can u refer me a book in which questions including answers related to these concepts are there for practice ... Thankyou sir 😊
Sir, when we have to apply this f-test. In 2nd vedio of F-test you said we have apply this test when 3 or more sample are given and right now you apply the same for 2 sample also... so this thing are confusing .pls clear when we apply this exactly this.
See video 2 there are two objective you are telling about 2nd objective, see also first objective. Apply F test 1. When you want to compare two population variance. 2. To compare mean of more than 2 samples.
Sir X² variables ki jgh Y variable bhi ho skta h kya or uske according S² ka formula bhi x ki jgh y value put ho skta h kya mtlb X² ki jgh Y name ho skta h kya
Sir one simple doubt in previous videos you were using one tail test, now you are using two tail test, will it be mentioned, or we should assume it please clarify, I know the video is uploaded long back, but however if u can answer it will be helpfull thnx
Because when our alternative is two sided, rejection region lies on both sides of tail. See below video of Hypothesis testing for more strong Concept. ruclips.net/video/xgxKFmBBj3U/видео.html
Check your concpet Null Hypothesis is Hypothesis of no difference so we assume that variance are same ( I.e. NO difference) in Null Hypothesis. Hope this will helpful.
Sir kindly help me I'm in very difficult situation.... One question came in SET Exam i will write it here What is the nature of F test? A. Essentially a two-tailed test B. Essentially a one-tailed test C. One-tailed or two-tailed test depending on the hypothesis to be tested D. Not a one-tailed test According to me the answer must be C.i.e. depending on the test, But according to answer key it is B. Sir if the answer C then I can challenge this question. Kindly refer me some authentic source to verify this that I can send them as evidence. Sir I will be very grateful to u.kindly reply.

Sir, whe we divide 5% by 2. Many videos show that we have to use 5% level not 5/2.
Because when our alternative is two sided, rejection region lies on both sides of tail.

thankyou sir
Just to correct one again on Two tailed behaviour of F test what you have taken is assuming symmetrical distribution
Don't know why 480 video quality option is not coming
It's coming please check again
At q3 why variance is not divided by df?

Null hypothesis ka statement both population variance are not equal hga ...and alternate mein equal hga
Check your concpet
Null Hypothesis is Hypothesis of no difference so we assume that variance are same ( I.e. NO difference) in Null Hypothesis.
Hope this will helpful.
sir one tail lena hai two tail ye kaise pta chalega?
How to differentiate between t test and f test like question for both the tests will be same so how come v will be knowing which to apply when
if they ask for check they have same variance or not then f test or we go for t test
