Question
In the assumed mean method, if A is the assumed mean, then deviation di is :
Answer: Option A
:
A
In statistics, 'theassumed mean' is a method for calculating the arithmeticmeanand standard deviation of a data set. It simplifies calculating accurate values by hand.
During the application of the short-cut method for finding the mean, the deviation d, are divisible by a common number ‘h’.In this case, the di = xi – A is reduced to a great extent as 'di' becomes dih.In this method,we divide the deviations by the same number to simplify calculations.The deviation is di=xi−A
