Discuss some ways that the concepts of covariance and correlation are similar or different.
natima [27]

Answer:

Step-by-step explanation:

<em>Key Differences Between Covariance and Correlation </em>

<em>The following points are noteworthy so far as the difference between covariance and correlation is concerned: </em>

<em> </em>

<em>1. A measure used to indicate the extent to which two random variables change in tandem is known as covariance. A measure used to represent how strongly two random variables are related known as correlation. </em>

<em>2. Covariance is nothing but a measure of correlation. On the contrary, correlation refers to the scaled form of covariance. </em>

<em>3. The value of correlation takes place between -1 and +1. Conversely, the value of covariance lies between -∞ and +∞. </em>

<em>4. Covariance is affected by the change in scale, i.e. if all the value of one variable is multiplied by a constant and all the value of another variable are multiplied, by a similar or different constant, then the covariance is changed. As against this, correlation is not influenced by the change in scale. </em>

<em>5. Correlation is dimensionless, i.e. it is a unit-free measure of the relationship between variables. Unlike covariance, where the value is obtained by the product of the units of the two variables. </em>

Ending time 6:30, elapsed time 37 minutes
Nastasia [14]

Answer:

5:53

Step-by-step explanation:

The original time would be 37 minutes before 6:30 so you would subtract 37 minutes from 6;30. So 6:30 minus 30 would be 6 and you would have 7 left over so 6:00 minus 7 minutes would be 5:53
