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
Median can be calculated from :
Individual series
Discrete series
Continuous series
All the above
Range is located by applying the following formula:
L - S
Q3 - Q1
______________ is not independent of scale
Mean deviation
Standard deviation
Quartile deviation
Mode
M.D. represents:
Median deviation
Marginal deviation
Mean
Semi- inter quartile range is also known as:
Quartile range
Middle value of series is known as:
Average
Median
Highest frequency
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.
L- S is the formula of calculating:
Range
Coefficient of range
