To calculate mean by assumed mean method, follow these steps:

♣ For each class interval, calculate the class mark x by using the formula,
xi = upper class limit + lower class limit/2

♣ Choose a suitable value of xi in the middle as assumed mean and denote it by A.

♣ Calculate the deviations di = (xi-A) for each value of i.

♣ Calculate the product (fidi) for each i.

♣ Find n = Sigma fi

♣ Calculate the mean, by using the formula,
Mean = A +(Sigma)fidi/n
