For the scatter plot, if the scatter is too high and we are not able to draw the line of best fit, we say the plot doesn’t show any correlation.

In A the scatter plot is rising and it is saturated on a rising line, so it is a positive correlation.

In B, we can draw a line fitting all the dots. Also it is rising. Hence it is a strong positive correlation.

In C, the scatter plot is coming down and we can still draw a line of best fit. So this is a negative correlation.

But in D, the scatter is in a huge area and we cannot draw a line around which it can be saturated.

Hence D shows no correlation.D doesn’t show a positive or negative correlation. D is the best answer choice.
