How do we get the assume value is it 1no + last Number by 2 and what value should we pick if our assumed value does match with others should we take the small number or the big number from the assumed value can you plz explain this to me
@@sheetaldeep ohh now I have understood thank q so the we can take any of the given value or if their is a option of middle value then we can take that too and we will get full Mark for that na
You're awesome ❤
Thank you so much
M= Middle value
d = deviation
A = Assumed value
d' = deviation dash
f = frequency

@sagarbiswas6418 Assumed value is mostly the middle value in the line ... But it can be any value as per your choice. As in my case, I have taken 25

Mam in which condition we use step deviation
A step deviation method is used in the case of the Continuous series where class interval is given like 0-5, 5-10, 10-15 and so on
A ??
A stands for Assumed Mean
Slow
Ok
How did u find A value
A is the assumed number or assumed Mean
You can assume any number as A
We have to assume any number from the frequency list, here the 25 is taken
Yes
How to find common factor?
Common factor is the difference between the range
like in this case
0-10, 10-20
the difference is 10-0 =10
20-10=10
@@sheetaldeep thank you
Thanks too@@sheetaldeep
What is c
C is common factor
Common factor is the difference between the range
like in this case
0-10, 10-20
the difference is 10-0 =10
20-10=10
why 25??
You can assume any other value to be Assumed mean. The calculation will differ in respect to that number.
