Covariance and Correlation Quiz

1. What does a positive covariance indicate about the relationship between two variables?

2. How is the correlation coefficient different from covariance?

3. If two variables have a correlation coefficient of 0.85, what can be inferred about their relationship?

What does a positive covariance indicate about the relationship between two variables?

Select the correct answer

The variables move in opposite directions.

There is no linear relationship between the variables.

The variables move in the same direction.

The relationship between the variables is undefined.

How is the correlation coefficient different from covariance?

Select the correct answer

Correlation is not standardized, while covariance is.

Correlation values are always between -1 and 1, while covariance can take any value.

Covariance is a better measure than correlation.

Correlation can only be used for sample data, while covariance works for population data.

If two variables have a correlation coefficient of 0.85, what can be inferred about their relationship?

Select the correct answer

They have a weak negative relationship.

There is no relationship between them.

They have a strong positive relationship.

They have a strong negative relationship.
