______________ is not independent of scale.
Mean deviation
Standard deviation
Quartile deviation
Mode
Q1 represents:
Lower quartile
First quartile
Both (a) and (b)
Neither (a) or (b)
Middle value of series is known as:
Average
Median
Highest frequency
Lorenz curve was first used by:
Marshal
Adam Smith
Fisher
Max Lorenz
For standard deviation, the relative measure is called
Coefficient deviation
Arithmetic mean
is used to calculate:
Decile
Octile
Quartile
Percentile
M.D. represents:
Median deviation
Marginal deviation
Mean
L- S is the formula of calculating:
Range
Coefficient of range
Write the false statement:
Range is the easiest and simplest measure because it is the difference between two extreme items.
Quartile deviation is superior to the range as it is not affected too much by the value of extreme items.
Range and quartile deviation are based on all the items of series.
Range and quartile deviation are useful for general study of variability.
Median can be calculated from :
Individual series
Discrete series
Continuous series
All the above
