Sir one marathon of top 10 questions per chapter in 2 session please ❤️ dhanyabaad sir for the session ❤️
28:42 median discrete 29:09 - Median for continuous distribution data 37:02 imp 41:54 ok ok 45:10 grouped aur ungrouped data ka dhyaan rakhna dono formula ka theek h 47:32 48:54 grouped me bas fi lagana h aur kuch nhi
Jiska SD kam wo consistent aur uniform h 52:18 coeff of variation maybe mains me aaye jiska zyada wo aur consistent h
54:18 ye ratne h 56:33 mean is not mean jo iske saath kro wo hojayega 1:12:02 good variety 1:16:24 mean aise nikalana is var me
var of 0 to n is n(n+2)/12 1 to n is n^2-1/12 first n odd or even natural no(jinme zero ni aata) n^2-1/3
1:25:53 aise mean nikal lo isme bhi pura cal ki zarurat nhi h
TYPE 4 sbse acha lga 1:36:41 ok 1:45:45 good ones 1:56:17 binomial se ache se
TYPE 7 really good formula ratlo

Amazing lecture sir you are best teacher of mathematics GOAT of mathematics 🎉❤
Tooooo awesome lecture sirr....tysm❤🤍❤🤍❤
Thank you sir could you please bring sessions on pnc and probability facing a lot of problem in pnc😢
True😢
@songcoc8469 are u guys doing reduced syllabys?
@@PrateekRajveer we don't have time for that
Sir kya mind blowing chapter padhaya aapne
Maja aagaya ❤❤

1:44:00
Exactly same question came in JEE MAINS 2024 ARPIL Session!!!
Literally the same!!!
Hands off to you sir!!!
The bestum best lec of statistics ever ❤❤
1:11:26 to neglect p as it is constant
1:15:00 understand it and type 2 ka koi ek example review
1:18:26 type 3 concept
1:45:14 watch this que
Thanks for your efforts i will continue with my efforts and try to get good rank ki jee mains ☺️
Kitna aaya bhai satisfied percentile bani
Jee 2025 reporting 🙋🏻
Best maths teacher of this era
After solving questions typewise confidence is at another level now !!
Thankyou so much sir ..... bahut maza aaya session me
Kha se
TQ SIR...........SEARCHED A LOT FROM EVERY WHERE ACROSS YT,,,,,,,AND GENUINELY FOUND THE BEST LECTURE
The mean and variance of five observations are 14 & 32 respectively there of five observations are 11,16&20 what are other two no.
54:50 we also can use the formula (Sigma)²= (d²(n²-1) )/12 where d is the common difference hope this helps 😊
The best part of this lecture was question practice session
1:24:15 3rd step me d add karke 1 2 3 4 5 6 7 banajar ek hi formula se kaam chala saakte hai
Sir and Ma'am plz help. My mind getting saturated again and again. Can't focus from last 7 days. Stress ho rha h bahut. Mock me number nhi aate to padhne ka man nhi krta. 💔💔
people were saying that calculations are lengthy and the chapter is very difficult so I left it till date, you proved it wrong sir, thank you very much sir, your teaching is made me feel that math is doable for me as well😀
The best mathematics teacher ever I seen way of teaching is super sir

⚠️SIR HY YOU DID NOT TEACH PROBABLITY DISTRIBUTION TABLE⚠️
Bro woh probability ke lecture main padha diya hain
Last section wahi padhaya hain
Thanks you sir,, ❤❤❤ ur lectures too much helps...
Type 1 HW 10 11 means option 1
thanku sir. you make everything seems so simple!
Trick to find common difference directly[by GB sir ] 1:26:11 by formula without involving a(1st term)
(Sigma)²=(n²-1/12)d²
d = common difference
n= no of terms
Kl exam hai 🤡🤡🤡
Was it helpful??
Tq sir ❤😇
Urs lect work as Confidence booster🤞🏻
loveyou sir...ittni acche se lec. liya hai and questions also..loveyouuu sirrr💗💗💗💗💗💗✨✨🙏🏻🙏🏻
