Which of the following set of data has least standard deviation?

Options

  1. A10 , 20 , 30 , 40
  2. B2 , 4 , 6 , 8
  3. C3 , 6 , 9 , 12
  4. D1 , 2 , 3 , 4

Correct answer

D. 1 , 2 , 3 , 4

Step-by-step solution

We know that, Standard deviation measures the spread of a data distribution. The more spread out a data distribution is, the greater its standard deviation. Here, from the options we see that the set 1 ,   2 ,   3 ,   4 has the least spread as data values are least far from their mean (Mean= 2 . 5 ) Hence, it has least Standard Deviation.
