Question

Geometric mean is a good measure of central value if the data are:

a) categorical b) on ordinal scale

c) in ratios or proportions d) none of the above​

Answer 1

on the ordinal scale is your correct answer

Answer 2

Answer:

c) ratio or proportions

Step-by-step explanation:

Geometric mean is an average which indicates the central tendency of a set of numbers by using the product of their values.

Geometric mean = $\sqrt[n]{x_{1} x_{2} x_{3} .........x_{n} }$

Ordinal Scale is defined as a variable measurement scale simply used to depict the order of variables. They are generally used to depict non-mathematical ideas such as frequency, satisfaction, happiness, a degree of pain, etc.

Example - Very Unsatisfied, Unsatisfied, Neutral, Satisfied, Very Satisfied.

Nominal Scale is the categorical variable scale which is used for labeling variables into distinct classifications. It doesn’t involve a quantitative value or order.

Therefore, Geometric mean is a good measure of central value if the data are in ratios and proportions.
