Lorenz curve was first used by:
Marshal
Adam Smith
Fisher
Max Lorenz
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.
Co-efficient of variation is located by applying following formula:
(S.D.)2
Range is the:
Ratio of the largest to the smallest observations
Average of the largest to smallest observations
Difference between the smallest and the largest observations
Difference between the largest and the smallest observations
_________ and______ are based upon deviation of values from the average.
M.D and S.D
Range and Q.D

Middle value of series is known as:
Average
Median
Highest frequency
Mode
Co-efficient of quartile deviation is calculated by applying following formula:
Q3 - Q1
Median can be calculated from :
Individual series
Discrete series
Continuous series
All the above
Mean deviation can be calculated with the help of following formula:
Semi- inter quartile range is also known as:
Mean deviation
Standard deviation
Quartile deviation
Quartile range
