Mean (M) and coefficient of variation (CV expressed as a percentage) of different datasets are given in 1 to 4 below. Compute the standard deviation of each dataset and arrange in ascending order.
- 1. M = 60, CV = 70/3
- 2. M = 80, CV = 6.25
- 3. M = 70, CV = 160/7
- 4. M = 90, CV = 40/9
A4, 1, 2, 3
B1, 3, 4, 2
C4, 2, 1, 3 ✓ Correct
D2, 4, 3, 1
Correct answer: (C) 4, 2, 1, 3 — Standard deviation equals coefficient of variation into mean divided by 100. For dataset 1 it is 14, for dataset 2 it is 5, for dataset 3 it is 16 and…
Explanation
★Standard deviation equals coefficient of variation into mean divided by 100. For dataset 1 it is 14, for dataset 2 it is 5, for dataset 3 it is 16 and for dataset 4 it is 4. In ascending order the standard deviations give 4, 2, 1, 3.
