Consider the following measures of central tendency for a set of N numbers : 1. Arithmetic mean 2. Geometric mean Which of the above uses/use all the data?

Options

  1. A1 only
  2. B2 only
  3. CBoth 1 and 2
  4. DNeither 1 nor 2

Correct answer

A. 1 only

Step-by-step solution

(i) Arithmetic mean = Sum of observation Number of observation (ii) Geometric mean = [n] Product of n observation Here, only Arithmetic mean measures central tendency.
