a percentage
b ratio
c same unit of data
d no unit​

Answer 1

Answer:

c same unit of data ... I hope that is right answer

Answer 2

Option D is correct, no unit

Given

• coefficient of correlation

To find

• to explain if the coefficient of correlation has unit or not.

Solution

we are provided with the coefficient of correlation and are asked to explain if it has any standard unit or not by providing reasons.

we know that correlation represented by r is primarily used to estimate the degree of relationship between two interconnected variables.

correlation coefficient, r is obtained by the dividing covariance of two variables and the product of standard deviation of the variables.

Since we are dividing covariance and standard deviation of two variables the unit of the variables get cancelled each other giving no unit to the correlation coefficient.

logically also, correlation coefficient is basically a number which denotes the relationship between two variables that varies between negative one to positive one. Since the number does not have any unit correlation coefficient also do not posses any standard unit.

option D is correct, no unit
