Mam u r great 😌🙏👏👏aap jis treeke se sikhtae ho aur hr wo choti chiz Jo students ko dikkt krti h😓 aapp unhe itte achhe se explain krti ho😌🥺 thanku so much mam thanku so much🙏🙏🙏
Mam apka padhane ke style acha lagta hai mujhe plzz mam moments skewness kurtosis , index number time series ka b vid banado plzz mam. Hamara exam aur 15 din me hai apka vid mujhe madat karta hai plzz mam banayiye
Hlo Mam Mam btao assumed mean se hum number kaise choose kare kyunki Koi b number lo Pr phir b answer nhi aa rha H mam Koi Trick toh btao Jiss se answer same aaye 🙏
@@ProfEvneetsCOMMERCECLASSES Mam jaise dekho yeh X series h 27,26,25,24,23,22,21, jismein unhone book mein 24 assumed Kiya h Aur Y series mein 22,21,20,19,18,15,10 h usmein humari book mein 19 assumed Kiya h Aur ap Keh rhe ho hum koi b le skte h no Pr Meine koi b no liya answer same nhi aa rha h mam mein kya karu 😭😭🙏
Mam jdo v mai..assume method nll given statement ch assume krke sum nikaldi ha sum da ans chnge aunda hai🙄 ...ki different assumption nll ans chnge ho jnda hai🤔... plz tell
Thanks alot ma'am but ma'am ek confusion hai jise humne Actual mean method mai small 'x' nikala hai toh ma'am fir short cut method mai small 'x' kyu nhi nikala ya fir mam jha X baar decimal mai aaega tab nhi nikalenge maam small 'x' plZ maam ye confusion hai aap muje btaae 🙏
Actual method me small x nikalte hai ...Lekin agar small x ( arithmetic mean) decimal me ata hai to calculation difficult ho jati hai further , isliye shortcut method lagate hai taki calculation easy rahe...exam me mention nahi hota ke yeh method lagaye ...Ye apki choice hai aap sidha shortcut method bhi laga sakte hai bina small x nikale....agar apko Actual method easy lagta to wahi lagao...it's completely your choice...
Mam kuj sums ch half shortcut method te half step deviations method nll sum solve kita hai...is it right???🤔 In simple words , ik variable da (d'x) lai ke solve kita hai te second variable da (dy) . It's confused me plz clear this doubt
Yes it is right but only in correlation as correlation is independent of change in scale...I have explained what is change of scale in correlation see this video 6 th point of difference between correlation and regression -th-cam.com/video/ctpPPzz6u0M/w-d-xo.html
a computer by calculating correlation coefficient between variable x and y obtained the following results N =30, ZX=120 ,ZX²= 600 ,ZY=90 ,ZY²=250 ,Zxy=335 it was however later discovered at the time of checking that it had copied down two pair of observation as X,Y :(8,10) (12,7) while the correct values are X,Y : (8,12) (10,8) obtain the correct value of correlation coefficient between X and Y.can u solve this?

Mam summation of dx is -3 but you written 3 there..

Hum assumed m direct method use kr skte h kya.
U are outstanding shukriya
Mam ap bhot acha phdate ho.. ap TR jain ki book ke mam unsolved exercise ki ve sum ki vinvd dalna plz mam👍❤️
Marvelous MAM...
Mam hum A first no. Ko mane to hazard positive and negative ka jhanjhat nhi rahta
Agar x ki mean value fractional he or y ki integer he to y direct method or x short cut method se kr sakte he kya ?
Yes, kar sakte hai but calculation thodi difficult ho jaegi...that's why we use assumed method
@@ProfEvneetsCOMMERCECLASSES thanks
Mam Yeh mujhe btao Fractional value ka kya mtlb h Please suggest me Kyunki Baar baar yhi sun rhi ho mein yeh baat
Hlo Mam Mam btao assumed mean se hum number kaise choose kare kyunki Koi b number lo Pr phir b answer nhi aa rha H mam Koi Trick toh btao Jiss se answer same aaye 🙏
Koi bhi number lo..answer same ata hai...aap calculation mistake kar rahe ho... koshish Karo ke x series se hi number lo assumed mean ka

good explanation madam
Well explained ❤️
Superb mam 🙏
Thank you maam
"A ,,ka value kya mean value ke nearest below number ya above number le sakte hai
Koi bhi le skte ho strting se last tk even 10 or 12 or 18 whatever uh want to
Mam actual direct aur assumed me agar long question Aya to answer tino ki equally ae ge
Mean nikalte waqt bhi hm assumed mean kuch bhi le akte ???
Yes
Yes
Mam how we get to know that which method we have to apply in case of Karl Pearson ?
It helped me a lot.. thanks ma'am 🥰🙏
Ma'am how u calculate the square root
Mam jdo v mai..assume method nll given statement ch assume krke sum nikaldi ha sum da ans chnge aunda hai🙄 ...ki different assumption nll ans chnge ho jnda hai🤔... plz tell
No..tum x ki value me se kuch bhi assumed mean le sakte ho...answer same aata hai...may be you have done some calculation mistake..
@@ProfEvneetsCOMMERCECLASSES ok mam.. thnkuu for reply🤗
Mam could u plss tell me how to take value of "A"
Take the middle most value
Why can't we use Direct method.? Any condition for using direct and shortcut method.?
Thanks ma'am
Thanks
Thank u so much mam🥰🥰
thanks mam
Mam agar hum kuch bhi assumed krte h to answer wahi aayega
Ye kaise pata chalega ki shortcut ya direct method se krna hai
Question mai diya hoga kya ?
You can use any method of your choice... answer will be same from all methods...it is never given in question which method to use
@@ProfEvneetsCOMMERCECLASSES thankyou 😊

Summation dx=-3 mam u wrote +3 then answer goes wrong mam
Yes...I have already corrected summation dx as -3 in video at 9:53 ..so the answer is correct.. please check

isnt that Standard deviation
Hlow Madam
1124.72 kesa hua
Mam aapne wo bataya jo maine kisi aur vidio me nahi dekha to mam
it should -3
in dx
Formula galat h.. N ko multiply nhi divide krte h

Madam it is wrong
please tell me mam
please use English
I will start new channel in English for students understanding English only....
Thank you very much mam ♥♥
