@@harshitarawat7330 sorry but jb mene ye question kra tha me uske 2 semester age agya hu plus vo notebook boht pehle fek di hogi mene 😂😂
Right ans 0.996 😇😇mera bhi aa gaye
@@shankyz73 okay, no problem
How did you solve it?
Answer is 0.996 ... THANK YOU so much mam 😊 for this helpful video 😊
Mam ye formula kb use kiya jata hai jaise point me aygea mean toh assumed mean use hoga and then ye formula kbhi bhi use kr skte ky??
I think yaha product mean method isiliye use kiya kyuki mean decimals mai aa raha tha toh actual mean method use hoga nhi but assumed mean bhi isiliye use nhi kiya kyuki x aur y ki values bohot choti thi whereas assumed mean hamesha jab x aur y ki bohot badi values hoti hai tab use hota hai dx aur dy nikal kar unko chota karne ke liye jisse formula mai values rakhna easy ho jaye.
if ham assumed mean use kro to kya galt h0ga??
@@arshstatus7864 I am not sure but I think ans toh aa jana chahiye assumed mean se bhi.Aap karke dekh lo agar ans same aa jaae toh assumed mean bhi use kar sakte hai

Mam how to know when to use this formula 😢

Mam i got 0.99
Mam ya formula kab use kar na hai
Mam ham dxdy vale formule se kyu nahi kr sakte ...
R=0.996
0.99 is the answer
Hello
Can you send me the solution of it.
Mam formula kaha pe konsa use krna h bahut confusion ho rha h... please help 🙏🏻
First check given X and Y values in question
next find mean of "X or Y" (sum of X values divided by N)
mean answer is without point, so formula apply "ACTUAL MEAN"
or
mean answer in point, so formula apply "ASSUMED MEAN"
And the "product moment method" is based on the question
(check X and Y values) and (check N is around 4,5,6)
@@meetgoswami8562 thankyou 😊
kab ye method apply karni hai ?
Mam book mein covariance topic h ek... Aapne voh ni kr aya?
