Which of the following is true of euclidean distances? a. it is used to measure dissimilarity between categorical variable observations. b. it increases with the increase in similarity between variable values. c. it is commonly used as a method of measuring dissimilarity between quantitative observations. d. it is not affected by the scale on which variables are measured.

It is commonly used as a method of measuring dissimilarity between quantitative observations

Step-by-step explanation:

Euclidean distance is an indicator of the true straight line distance in Euclidean space between two points. There is only 1 Dimensional space in an illustration where there is only 1 variable representing each cell (or case). The simple arithmetic difference will be the Euclidean length between two cells.

Hence the correct answer is

Euclidean distance is commonly used as a method of measuring dissimilarity between quantitative observation.

So Answer is (c).

add the table and i will answer correctly
