Aren’t we suppose to choose U which is minimum of U1,U2 i.e. U=min[U1,U2] instead of deciding the value of U by number of samples? there might be a mix up with Wilcoxon Rank sum test. Can someone put some light on it? Thanks
Thank you so much ma'am ❤️ kyun class me teacher itna accha nhi pdate jbki me govt. College me pdta hu or yha ke techer bale hi well qualified ho but vo sayd pdana nhi chate he ☹️
n1=12, n2=12, R1=101, R2=199, u=121, Mean =72, S.D=17.32 Z=2.32 Z≤1.92 but here Z = 2.83, which is greater than 1.96 ,so HO is rejected ..... Is it correct?
n1=14, n2=14, R1=101, R2=199, U=200, Mean=98, s.d=21.76, z=4.69, z>1.96. So,H0: is rejected. But my question what should we take as H0:?? And thanks for the videos👍😊

Yes correct. Thanks for your support. Please check out the whole playlist : th-cam.com/play/PLsmamMNLjMzVlML3a49ZAMjxlMTTZYgpT.html Also share with your friends.
No it's wrong. H0 is rejected here. Please write down the value of Z also. And if H0 is accepted then H1 will be rejected, only one can be accepted at a time

Nice explanation mam well done 😊
Nice explanation mam
Asslam o alikum mam mujhe wilcoxon sing test ki video nhi mil rhi ..kindly sahre link
Best explained
Thanks for helping us
Mam app run test ke upper video bna dijiye
Mam if n= more than 20 ....ho to same formula hi use hoga kya .?🙏🙏
Plz tell me mam
Yes
Thank you so much ma'am ❤️ kyun class me teacher itna accha nhi pdate jbki me govt. College me pdta hu or yha ke techer bale hi well qualified ho but vo sayd pdana nhi chate he ☹️
Why u don't do for U' calculation or this mean Nd SD after that z calculation is applied for all sums ? and n1×n2=U+U'?
Perfect ❤thanks a lot ❤
Lastly jo z value 1.96 kanha se aya plzz bataiye
Thank you ❤
Ma'am is chapter k all test ki MCQs mil jaen hi kya please
Agar hme sequence diya ho tab hm kaise obtain karenge Mann Whitney Wilcoxn test for example
Y4
Assign ranks in ascending order 1,2,...n then solve.
THank you so much mam
Mam please make a video for run test
ANS : Z = 2.83
H0 is Rejected .
You helped me a lot in my exms.. thank you
Some sums are( comparing with z test or critical u table) which one is used for particular data
Mam , the sum that you solved , the value of mean should be 25.5 , bcz 72+36-83.5. It gives 25.5
Agar Critical Value Table Na ho To Kya Karen???
mam kruskal Wallis test bhi sol kro 😊
n1 and n2 both same ho to konsa formula lena he U kliye?
Anyone
If n1 ans n2 are same which condition should we take
Ho=Regular sale and sale after free sample are equle m1=m2
So tell me what i write in H1?
In that case, H1 : m2 > m1
Because we will assume the increase in sale after free sample
Plz help me stat me kt nai soal ho rahi sem 6 stat ki kt
In some cases n1=n2. so which formula we can use from 1 and 2.Because R1 and R2 is different .
Formula 1 we have to use when N1 = N2
Mam mcq exam ke liye question paper set banayiye n plz🙏
Thank you
Kruskal waliis h test do explain please
Mam short question kaise honge iske
Hi mem N1=N2 who do calculated R value
U = 121,
mean =72,
S.D = 17.32,
Z = 2.82
Difference is not significant
Yes correct
Mera bi yeh hi answer h correct
What if there are 3 numbers while giving the rank
n1=12,
n2=12,
R1=101,
R2=199,
u=121,
Mean =72,
S.D=17.32
Z=2.32
Z≤1.92 but here Z = 2.83, which is greater than 1.96 ,so HO is rejected .....
Is it correct?
Yes correct
But mera u 23 hi aa raha he
n1=14, n2=14, R1=101, R2=199, U=200, Mean=98, s.d=21.76, z=4.69, z>1.96.
So,H0: is rejected.
But my question what should we take as H0:??
And thanks for the videos👍😊
n1 and n2 are 12 , not 14. So your answer is coming wrong.
And hypothesis is there is no difference between regular sale and sale after free sample
@@statisticsforall3433 H0:there is no difference between regular sale and sale after free sample
n1=12, n2=12, R1=101, R2=199, U=121, Mean=72, s.d=17.32, z=2.82, z>1.96.
So,H0: is rejected.
Is it correct now?

Thank you 🙏🏻 mera presentation v aacha jayega app ke waje say..🙏🏻
Plz put the ans for the that last extra question
H0: accepted why H1 kyo ni tell me answer madam plg
No it's wrong.
H0 is rejected here. Please write down the value of Z also.
And if H0 is accepted then H1 will be rejected, only one can be accepted at a time
Mam 8+9+1= 8 kese huye?
Z \2.82
what if the level of significance is 2%..........?
Then compare the value of Z with 2.33
Ma'am (-1.11) hoga
Z=2.82
H0 is rejected
2.83
Z=2.83
Ho is rejected
Yes correct
@@statisticsforall3433 thank you ma'am ye aapki mehnat he.. 😊
Z=2.83 ho is rejected
Ma'am is chapter k all test ki MCQs mil jaen hi kya please
what if the level of significance is 2%..........?
Z = 2.8290
Ho is rejected
what if the level of significance is 2%..........?
