Question

If two variables, V1 and V2, are used for clustering. Which of the following are true for K means clustering with k =3?

If V1 and V2 have a correlation of 1, the cluster centroids will be in a straight line

If V1 and V2 have a correlation of 0, the cluster centroids will be in a straight line

Select the correct answer from below options: 

A. 1 only

B. 2 only

C. 1 and 2

D. None of the above

Answer 1

Answer: (A)

If the correlation between the variables V1 and V2 is 1, then all the data points will be in a straight line. Hence, all three cluster centroids will form a straight line as well.
