Some measures of central tendency for nn discrete observations are given below: 1. Arithmetic mean 2. Geometric mean 3. Harmonic mean 4. Median A desirable property of a measure of central tendency is if every observation is multiplied by cc then the measure of central tendency is also multiplied by cc, where c>0c > 0. Which of the above measures satisfy the property?

Options

  1. A1,2 and 3 only
  2. B1,2 and 4 only
  3. C3 and 4 only
  4. D1,2,31,2,3 and 4

Correct answer

D. 1,2,31,2,3 and 4

Step-by-step solution
