The correlation coefficient of −0.2 say about the graph is x and y have a weak, negative correlation option (D) is correct.
What is correlation?
It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]
The missing scatter plot is attached to the picture, please refer to the picture.
We have a scatter plot shown in the picture.
When the points are not roughly aligned, the argument is deemed weak. The line is regarded as negative because it runs from left to right.
As the correlation coefficient is -0.2
The above value represents the x and y have a weak, negative correlation
Thus, the correlation coefficient of −0.2 say about the graph is x and y have a weak, negative correlation option (D) is correct.
