Standard deviation gives us a standard value of deviation with respect to arithmetic mean ... Mean deviation gives us deviation values with respect to either arithmetic mean or median.
Even or odd ka case individual series m dekhte h ...discrete and continuous series m hum cumulative frequncies nikalte h to N/2 se answer nikal aata h.
@@MehwishHaqnawaz-q5m yes ..this is median of continuous series (frequency distribution) I have used same formula which you mentioned but with little variation.
Hum yahan series ko 2 nhi 4 parts m divide kr rhe h (quartile means 4 equal parts)... So N/4 hota h Median m 2 parts m divide hoti h series to N/2 hota h.

Continuous series m ek hi formula use hua h ..formula k according aap sabse pahle ek hi value find out kr skte ho jo h n/2 ...wo value milne k baad aap cumulative frequency m us value ko locate kro than rest items find out kro ...itna krne k baad values ko formula m put kro jo value aayi wo aapke question ki item m find kro and uske samne wali cumulative frequency ka data hi aapke question m diye gye data ko exactly half m devide krega ..
Because the even and odd case considered only in individual series ..rest two series gives u a cumulative values, so we can use different formulas for different series.
@@paramjeetkaur890 so discrete k liye bas odd and even type ka median formula use krenge. And continous k liye bas N/2 krna hai median class find out krne, right ?
@@30pranaypawar17 individual k liye two formulas...discrete series k liye only( n+1/2) formula and continuous series k liye n/2 find out kr k direct formula values ..

maam ur statistics videos are saving me for tomorrows exam hats off to you maam thank you so much
Thanku mam

What is difference between mean deviation and standard deviation
Standard deviation gives us a standard value of deviation with respect to arithmetic mean ... Mean deviation gives us deviation values with respect to either arithmetic mean or median.
Asuumed mean was selected in wrong
for even data , [size of (n/2)th + (n+1)th/2]/2
No ..its size of ((n/2)th item +((n+2)/2)th item )/2
Or you can use size of (n/2)th item It gives you a decimal value which gives you idea about median value
How to find d i know its formula is m-a but how to assume number in x given like 0-10,10-20,20-30,30-40,40-50 ???
Use mid value for this
Beautifully explained sister
Best education ❤❤❤

Even m b same aise hi calculation krni h.

Hmne n/4 ku liya wese n/2 hota h na
Hum yahan series ko 2 nhi 4 parts m divide kr rhe h (quartile means 4 equal parts)... So N/4 hota h Median m 2 parts m divide hoti h series to N/2 hota h.

Aapne n/2 kyon use kiya and cf uske before wala kyon choose kiya ?
Continuous series m ek hi formula use hua h ..formula k according aap sabse pahle ek hi value find out kr skte ho jo h n/2 ...wo value milne k baad aap cumulative frequency m us value ko locate kro than rest items find out kro ...itna krne k baad values ko formula m put kro jo value aayi wo aapke question ki item m find kro and uske samne wali cumulative frequency ka data hi aapke question m diye gye data ko exactly half m devide krega ..
Kyunki agar hum aisa na krte to data double count ho jata ..
N ki value hi hum locate kr skte the is formula k base pr and uske baad use half m devide kr k hum next values nikal skte the
@@paramjeetkaur890 ohh ok.
Abhi ismein n even number hai = 30. So even median wala formula kyon nahi use kiya - n/2 th + (n+1) /2 th
Because the even and odd case considered only in individual series ..rest two series gives u a cumulative values, so we can use different formulas for different series.

Thanks ma"am you my exam is today
All the best 👍
Thanks for revise me 😑😍

Thank you ☺️
Excuse me 74 /2 is 37 not 32
She did that in the end
Hlw miss suppose that total number of sum CF odd obtained then which formula apply?? Reply us I am waiting for msg
You can use N+1 in place of N..
36 hai bro
37 is correct.
chii
Thanks mam 😘
Why there is no minus sing when subtracting from smaller number to higher
"|.....|"- these two bars denote deviation from mean ignoring signs... For more clarification watch my video of 'what is mean deviation?.
Thanku
Mam discreet series mein order Mein arrange karte hain?
Nhi...discrete and continues serious m data ka arrangement already hota h to use arrange nhi krte
Aapne N ki value 9 kyu liye?
N means the number of items. In this case 9,5,8,7...these all are 9 in number that's why we take N=9.
Thanks mam ❤️
Most welcome 😊
Thanks mam 🤝🏻
Plz reply me mam
I have understood everything but at end of the problem u have to tick 48,52,56 but u have ticked 48,52,56 and 60; why mam ..?
It's a mistake..plz consider only 3 values
Thank you so much mam I have clear my dought
