Awesome work 👏👏
Fx² k liay pehly x² ka individual square hota jai phir f k sath × toh fx² bnta hai 🙃
You are a good teacher
Thank you please share with your friends and classmates 🤗
Sir without calculator calculate kr skte hai kya.in many exam Calculator not allowed.
Thank you so much sir 🙏🙏🙏
Your most welcome 🤗 can you please share this video with your friends and classmates 🙏 keep supporting this channel and ask question frequently
Thanks sir for providing valuable time and efforts ❤

@@aryaanjum1 ok sir ❤❤
Thank you 😊
Make next video on mean deviation
Okay 🤗
Sir mujhe btaye Agar Calculate Coefficient of variation of the following Distribution Diya hoga toh toh agar Question Aisa aaye toh use kaise kare please sir btaye jaise

Coefficient of variation ka Matlab hai standard deviation ka square karein.......eiska Mai alag se ek video bana Dunga🤗
@@aryaanjum1 ok Sir Thanks 👍🙏

Are sir problem ko dusre type se solve kar sakte hai kya
Haa bilkul kar sakte hai
Super 🎉

@@aryaanjum1 ☺
Thank you
Hello mam 🙋 ...u did wrong
How can we get 695.04 after dividing by 22 ...its 26.36 right...
Yes it's right but there is square then you have to square (26.36)^2 =695.04
Watch again it's right
🎉
Bhai esa cllg mei kraya hi nhi 😂
Samajh hi ni aara😢
Yasma ta questions youta ani solution youta gara xa ne yasto Pani hunxa ra

Yasari
Ar aap ye to btiye kon sa method se kr r eh 😢😢 direct , h na ??
Ji bikul ye direct method hai....
Aap exam mein koi bhi method se standard deviation bana sakte hai kyunki
Exam mein shortcut method se banaye ,step deviation method se banaye or direct method se banaye bolke nahi poocha jata hai to aap Kisi ek method se bana sakte hai
👉Sabse asaan method direct method HOTA hai to aap bhi direct method use kare
What if f in has minus numbers...?
Waisa question nahi aayega ji don't worry.......and please share this video with your friends and classmates agar accha laga ho to
Why the frequency is like that way? Plz make me understand
Because
0-10
0-20
0-30
0-40
Or
20-40
20-60
20-80
20-100
Eis type se jab question ho tab
Frequency nahi dekar cumulative frequency diya HOTA hai ......name frequency bhi de fir bhi usko cumulative frequency hi suppose kare
If question aisa hoga toh
👇👇👇👇👇
0-10
10-20
20-30
30-40
Or
20-40
40-60
60-80
80-100
Eis time frequency hi fiya HOTA hai usko frequency hi let karenge🥰
Tnxq 😊
🤗 welcome
Hello sir
Yes please
I have a question
Ok you can ask
In previous video aapne frequency same rakhi or is video meinapne frequency alga tarah se Rakhi?..??.
Good question
Agar question eis Tarah se hai tab frequency diya HOTA hai f ko f mein hi place karenge
0-10
10-20
20-30
30-40
40-50
But
Agar question
0-10
0-20
0-30
0-40
0-50
Eis Tarah se ho tab frequency dekar aapko confuse karega
Wo frequency nahi HOTA hai wo c.f HOTA hai
Agar eis type ka question ho to frequency ke place mein subtract karke karna padta hai
@@aryaanjum1 got it..thank you so much sir
Your most welcome 🤗 can you please share this video with your friends and classmates 🙏 keep supporting and keep watching
@@aryaanjum1 sure!😊
Thank you
Mam mid vlue ap glt bna r h r frequency b
Dekhiye ye ekdam Sahi hai.....aapka class interval
0-10
0-20
0-30
Diya gaya hai
Aise class interval mein video ki Tarah same to same nikale
😮😮😮
Please share with your friends and classmates 🙏
😮
What happened?
Frequency to d Hui h na to q nilkaange hm log 😢😢😢😢😢
Agar question mein class interval aisa ho to
👇👇👇👇👇👇👇
0-10
0-20
0-30
0-40
0-50
Or
10-20
10-30
10-40
10-50
10-60
us wakt frequency diya gaya ho to usse cumulative frequency manenge and frequency nikalenge minus (-) subtract karke....
If question aisa ho to
👇👇👇👇👇👇
10-20
20-30
30-40
40-50
50-60
Aisa question ho to frequency ko frequency hi manenge
Comulative frequency Di hai To Usse Frequency Me convert kia hai
Mat isliya hard hai
Frequency ap glt likhe h jo question me vo Kyu nhi likhe h
Sir, does it mean that cummulative frequency was given in the question from first and then you obtained frequency ??
Right .....that was cumulative frequency so we have find frequency first in that type of question....
Some times question makes you confused by giving name frequency besides of cumulative frequency
Thank you, sir.
Most welcome 🤗 can you please share this video with your friends and classmates 🙏
If u knew why u still watch?
14 may ko mera exam h
Best wishes from our side....🤗
Plz one video for the standard deviation using actual mean
Sir there should be x² after mid value.❤❤
Aapko video mein jaisa dikhaya gaya waise bhi kar sakte hai .....dono right hoga....don't be confused
Tqms🌸😚
🤗 welcome keep watching 🤗
Questions samj ni aa ra h you

Hello sir this question is direct method?
Yes this is direct method......
Sir your calculator full name. I want to buy this
Casio fx99Eplus
Can you please share this video with your friends and classmates 🙏
@@aryaanjum1 ok sir Don't worry
Thank you 😊
Ye 25 square kaise likhe sir calculator me mere me to hai nhi
Nahi hai to 25*25 kare
Do bar 25 ko multiply karle
And please share with your friends and classmates
Your voice is very slow
Ok it will be considered in next video.....can you please share with your friends and classmates
hlw mam, in the list, 0-10, 0-20, i think it was typing mistake.
btw, excellent video
No question typing is not mistake.....
If that type of question will asked in ur examination....solve like this video ok....
oh! Yeah, I saw this video again, & understand finally, thanks mam
Welcome 🤗 I m not mam🤣 it's me sir
@@aryaanjum1 Ha ha, sorry Sir!
Sir fx² ye nhi samjh aya kaise nikala q ki fx tu 20 hai tu fx² 400 hona chahiye
fx^2= 4*5^2 =4*25 =100
Please repeat dekhe....samjh jayenge
Pr sir hame tu sir ne fx² mtlb 20² = 400 aisa bataye hai tu ham kya kre batao q ki mera Monday ko bored exam hai
@@priyadubey9872 sir ne galat sikhaya hai bhai tujhe.. fx² 400 nahi hoga.. 100 hi hoga
Bro there is not f^2x^2 only here fX^2
Deviation kahan liya
Ye direct method hai...eisme devian Lena nahi parta hai....aap standard deviation with step deviation ka baat kar Rahe hai......
this video is done by direct method so eisme deviation nahi hoga...aap eis tarah se bhi solve kar sakte hai
@@aryaanjum1 galat hai kyoki standard deviation bina deviation liye nhi ho skta hai chahe wo actual mean se liya ho ya assume mean se, aap standard deviation fir se padhiye
Ye direct method hai ji.....aap Kisi bhi method se banaye answer yahi aayega ji
First one u did wrong in fx2
It's not mistake.... please calculate properly🙏
20 ka square 400 hoga na
20 ka square nahi x ka square ha... F=4, x=5 f*x² = 4*25=100
Thank you 🙏🙏🙏🙏😊
Fx2 means f.(x)2
Medam 20×20=400 fx2 and 45×45=2025
Waisa nahi karna hai....aap f *x^2 karein........
f=4 hai
X =5 hai
So,
f*x^2 = 4*5^2 =4*25=100
F ko thik to likhlo 😂😂😂😂😂😂😂
Ok ji next time🤗
Plz share with your friends and classmates
Are Masab frequency hi wrong likh rahe ho ap😡
Arey Bhai eismie frequency given nahi hai wo c.f hai aapko eis Tarah se dekar question ghumakar diya hai
😂😂
Can you please share this video with your friends and classmates 🙏
Ye video ko biswas na kare , ye AI editting hunda hain
Ye AI editing nahi hai ji.....100 % right hai ye
And please share this with you and classmates 🙏
frequency kina ysari nikaleko? frequency ta jasto xa testai lekhne hoina ra?
Yadi question ma class interval yasari deko xa bhane:-
0-10
0-20
0-30
0-40
0-50
Or,
10-20
10-30
10-40
10-50
10-60
Yasto question ma frequency deko hudaena bujhnu bho
Yasma,
cumulative frequency (c.f) given deko hunxa so frequency nikalne (-) subtract gari gari ....
But
If question yasto hunxa bhane,
0-10
10-20
20-30
30-40
40-50
Yasma frequency deko hunxa yasma ghatauna pardaena.....
Hamare channel pe do video hoga wo slowly dekhe Pura dekhe samjh jayenge
@@aryaanjum1 now i'm clear. Ok Thank you 🙏
Welcome 🤗
Aata nhi hai to video banate hi kyu ho
You are writing wrong mam
No this is not wrong.....this is called as direct method of standard deviation
Sir app ko hindi nhi aaati
Yes my Hindi is very weak..... because I am nepalese 🤗
