Formula for assumed mean
WebAs a result, the formula for calculating the mean using the assumed mean technique is: Mean (x) = A + ∑fidi / ∑fi Here, fi = ith class’s frequency A = assumed mean Σfi = N = … WebAssumed Mean A: Pick the median value from the class marks and indicate it as A. Column 3: Determine the relevant deviations using the formula di = xi - A. Column 4: Frequencies (fi) (corresponding) Column 5: Mean of di = ∑xidi/∑di. Finally, calculate the Mean by adding the assumed mean to the average of the di.
