Answer 2

The correlation coefficient has the unit of zero representing X measured in hours and Y measured in minutes.

Definition of correlation coefficient;

Correlation coefficient represents the specific measurement of the relationship between the two variables in a correlation analysis.

Types of correlation coefficient;

1. Positive correlation coefficient- the value of one variable increases with the another variable.
2. Negative correlation coefficient- Here the value of one variable increases with the another variable decreases.
3. No correlation-  when there is no linear relationship between the two variables.

As the correlation coefficient given is in X and Y representing minutes and hours then there is zero unit.

Therefore, correlation coefficient does not have any units. It represents the number.
