Which of the following is not a measure of central tendency?
Median
S.D
Mean
Mode
The variance of 10,10,10,10 is
10
√10
5
0
Given and n = 12. The coefficient of variation is
25
20
30
If the SD of a set of data is 1.6, then the variance is
0.4
2.56
1.96
0.04
Mean and SD of a data are 48 and 12 respectively. The coefficient of variation is
42
28
48
The range of the first 10 prime numbers 2,3,5,7, 11, 13,17,19,23,29 is
26
29
27
Coefficient of range is calculated using the formula
L - S
L + S
The greatest value of a collection of data is 72 and the least value is 28. Then the coefficient of range is
44
0.72
0.44
0.28
The median of 13,23,12,18,26,19,14 is
18
23
SD of a collection of data is 2√2. If each value is multiplied by 3, then the SD of the new data is
√12
4√2
6√2
9√2
