Funtley Deviation ended in 1974.
Funtley Deviation was created in 1906.

What is mean deviation and why is quartile deviation better than mean deviation?
Information is not sufficient to find mean deviation and standard deviation.
mean deviation =(4/5)quartile deviation
The mean average deviation is the same as the mean deviation (or the average deviation) and they are, by definition, 0.
None.The mean of a single number is itself.Therefore deviation from the mean = 0Therefore absolute deviation = 0Therefore mean absolute deviation = 0None.The mean of a single number is itself.Therefore deviation from the mean = 0Therefore absolute deviation = 0Therefore mean absolute deviation = 0None.The mean of a single number is itself.Therefore deviation from the mean = 0Therefore absolute deviation = 0Therefore mean absolute deviation = 0None.The mean of a single number is itself.Therefore deviation from the mean = 0Therefore absolute deviation = 0Therefore mean absolute deviation = 0
No. The average of the deviations, or mean deviation, will always be zero. The standard deviation is the average squared deviation which is usually non-zero.
No. The mean deviation is 0. Always.
Because the average deviation will always be zero.
The standard deviation is the standard deviation! Its calculation requires no assumption.
