Assignmnt no 2 mn x hamen dia hoa ha but f ki tu hamen zarorat ne hoti mean deviation mn. plzz clear my concept. i mean f ka kia karna ha?
again wrong...
you should not take sum of them..
here sum of f = 30..
make frequency dist.
class limits | f | Rf
these r the column
ayisha ic m just class limits ka colum aye ga ya class bundries ka b aye ga
i think bana phry ga q k ques main frequency distribution table ka kaha gya hi aur table main ye sub ate hi
nhi class limits aur class boundries ka column nhi ae ga
total 5 columns banen gy:
class limits
frequency
tally marks
relative frequency
% relative frequency
regards.....
to calculate mean deviation we have to use this formula:
M.D=Ʃǀdiǀ
n
please correct if i am wrong
regards.....
Kia hamein Cumulative frequency ka column banana hai?
no brother we don't need to make the column of cumulative frequency.
regards.....
yes
thanku dear i hope isi tarah sari assignment sahi se ho gye i m sharing our views tomorrow
M.D ka mera ans hai 0.3727 is it correct or not ????
