Two sets of data that show a relationship is an example of correlation.
<h3><u>
Explanation:</u></h3>
Correlation is the relationship between two sets of data. Correlation in statistics help in determining whether two or more sets of data fluctuate in accordance with one another or not. And if they do, the degree of fluctuation can also be determined and studied.
By determining how one or two variables or data are related to one another, we can understand how to manipulate the values. In correlation, there are following possibilities:
- When one value increases, the other decreased
- When value increases or decreases, the other changes in the same way.
Example of correlation:
