The formula for finding the mean through assumed mean method is:
Mean = A + ∑fidi/∑fi
A = Assumed Mean
d = (xi - A)
∑fi = Total Frequency
∑fidi = product of frequecy and (xi - A) i.e. di
Mean = A + ∑fidi/∑fi
A = Assumed Mean
d = (xi - A)
∑fi = Total Frequency
∑fidi = product of frequecy and (xi - A) i.e. di
