Best answer

Steps: Estimating MD through Median	Steps: Estimating MD through Mean
(1) Arrange the data in ascending order.	(i) Calculate arithmetic mean by adding up the data.
(ii) calculation the median M size of ((N+1)/2)^th term	(ii) Find out the deviation of the items from mean. Ignore (+) and (-) signs. Express it by \|d\(\bar x\)\| sign
(iii) Find out the deviation of the items from median. Ignore (+) and (-) signs. Express it by \|dm\| sign	(iii) sum up the deviations
(iv) Sum up the deviations, and express the same by Using the relevant formula to find the required answer. MD_m= Σ\|dm\|/N	(iv) Use the relevant formula to find the required answer. \(MD_{\bar x}=\frac{\sum\|d\bar x\|}{N}\)
(v) After that solve the question with the help of the formula.

Calculation of mean deviations
sum up the deviations
