Middle value of series is known as:
Average
Median
Highest frequency
Mode
cf is used for:
Common factor
Cumulative frequency
Common value
None of above
Mean deviation can be calculated with the help of following formula:
Co-efficient of variation is located by applying following formula:
(S.D.)2
M.D. represents:
Mean deviation
Median deviation
Marginal deviation
Mean
Q3 can be calculated from:
Semi- inter quartile range is also known as:
Standard deviation
Quartile deviation
Quartile range
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
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.
L- S is the formula of calculating:
Range
Coefficient of range
