Question

anyone explain me assumed mean and step deviation method please ​

Answer 2

Answer:

In statistics the assumed mean is a method for calculating the arithmetic mean and standard deviation of a data set. It simplifies calculating accurate values by hand. Its interest today is chiefly historical but it can be used to quickly estimate these statistics.[1]There are other rapid calculation methodswhich are more suited for computers which also ensure more accurate results than the obvious methods.

 Step  Deviation Method (Mean)

Step Deviation : Sometimes, 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 di / h.
