Your videos are simply outstanding. I have only one question. While conducting F test, F statistic is usually given by Sa2/Sb2. However, while deriving the pdf of F distribution two independent variables' (with some dof) ratio are considered with χ2 distribution. How do we come to know that σa2 or σb2 follows χ2 distribution? Otherwise, S2/Sb2 ratio cannot be expressed by F statistic.
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.

Nice 👍👍👍
Sir I think there is n1-1 and n2 - 1 in the formula where s1 and s2 given
Yes
🤘🤘

With the help of this ratio what is conclusion.
