[@AbhishekMalviya-ki7rx]

while watching i got confused ansd come here to comment but here you cleared .
thank you so much.

[@souradeepdey5004]

[@kim-kw3wu]

​@@AbhishekMalviya-ki7rxfail to reject instead of reject what is the meaning of this ???

[@tusharkhatri5795]

@DrHarishGarg in 18:49 H0 should be rejected not fail to be rejected since tabulated value < calculated value and its both tailed 11.5>5 means h0 should be rejected please clarify this

[@moodenhancer4803]

sir when when n1 & n2 both are equal to 10 then it will be considered large sample or small sample?

[@madhulikasingh2047]

What if smallest number have multiple entries then should we start the rank with one or mean of it?

[@abhijeetkumarmaurya4697]

Sir in my book min(Ux,Uy) is not given...can you please send me your notes

Sir in first sum why you dont use the z formula z= U-E(U)/√v(u). I don't understand then u are using this formula at the end of the sum ???

In the example for large sample, it is given median salary of education is lower than median salary of marketing. So null hypothesis should be nx=ny
Please check

Sir have you calculated the value of Tx+Ty using values of Tx and Ty from the formula of Ux and Uy.
If so then Tx + Ty would be {(n1+n2) (n1+n2+1)}/2
It will be +1 not -1
Please confirm me as soon as possible

Sir, firstly I would like to say that the way of your teaching is excellent, but sir if calculated value is greater than critical value (tabulated value) then it should be rejected, all the students will be confusing in it because sir you have rejected in both case, plz look it sir again.
