Answer
Option D is correct.
Step-by-step explanation
A positive correlation coefficient indicates that the graph of the data is positive sloping.
The closer the correlation coefficient is to 1, the more perfectly positively correlated the data is.
The farther the coefficient is from 1, the more scattered the data is; although, since it is positive, we can still see that it is positively sloping amidst the scatter.
A negative correlation coefficient indicates that the graph of the data is negative sloping.
The closer the correlation coefficient is to -1, the more perfectly negatively correlated the data is.
The farther the coefficient is from -1, the more scattered the data is; although, since it is negative, we can still see that it is negatively sloping amidst the scatter.
For this graph, we can see that the graph is positive sloping and the data points align on multiple straight, positive sloping lines. So, we can see that the correlation coefficient is not 1, it is more appropriate for it to be 0.5.
