Semi- inter quartile range is also known as:
Mean deviation
Standard deviation
Quartile deviation
Quartile range
_________ and______ are based upon deviation of values from the average.
M.D and S.D
Range and Q.D
S.D and Q.D
M D and QD
Median can be calculated from :
Individual series
Discrete series
Continuous series
All the above
is used to calculate:
Decile
Octile
Quartile
Percentile
Co-efficient of variation is located by applying following formula:
(S.D.)2
Mean deviation can be calculated with the help of following formula:
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.
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
Middle value of series is known as:
Average
Median
Highest frequency
Mode
Range is located by applying the following formula:
L - S
Q3 - Q1
