Mean deviation can be calculated with the help of following formula:
cf is used for:
Common factor
Cumulative frequency
Common value
None of above
L- S is the formula of calculating:
Standard deviation
Range
Coefficient of range
Mode
Median can be calculated from :
Individual series
Discrete series
Continuous series
All the above
is used to calculate:
Decile
Octile
Quartile
Percentile
Range is located by applying the following formula:
L - S
Q3 - Q1
______________ is not independent of scale.
Mean deviation
Quartile deviation
_________ 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 Q.D
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
which of the following statement is NOT true
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.
