Question

If di is the deviation of a class mark yi from 'a', the 'assumed mean' and fi is the frequency, then Mg = x + (1/∑ fi di), then x is (A) lower limit (B) assumed mean (C) number of observations (D) class size

In the given formula 'x' is the assumed mean 'a'.

Q. If di​ is the deviation of a class mark yi​ from 'a', the 'assumed mean' and fi​ is the frequency, then Mg​=x+∑fi​di​1​,thenxis

lower limit

assumed mean

number of observations

class size

In the given formula 'x' is the assumed mean 'a'.

Q. If $d_{i}$ is the deviation of a class mark $y_{i}$ from 'a', the 'assumed mean' and $f_{i}$ is the frequency, then $M_{g} = x + \frac{1}{\sum f _{i} d _{i}}, t h e n x i s$
