Which of the following characteristics of a data set are understood using the Karl Pearson coefficient of variation?

A. Disparity

B. Consistency

C. Uniformity

D. Homogeneity

E. Unbiasedness

Choose the correct answer from the options given below:

The correct answer is A, B and C only.

Key Points A. Disparity
The coefficient of variation (CV) measures the relative variability or disparity of a dataset in relation to its mean. A higher CV indicates greater disparity or variation in the data set.

B. Consistency
In the context of the coefficient of variation, consistency refers to the degree of relative stability or consistency of the data set. A lower CV suggests more consistency or stability in the data, as it indicates a smaller ratio of variation to the mean.

C. Uniformity
The coefficient of variation can also provide insights into the uniformity of the data set. A lower CV suggests a higher level of uniformity, as it indicates a smaller relative variation compared to the mean.

Hence, the correct answer is A, B, C.
