Statistics

• Positive Correlation - trend of data points has a best line of fit that is positive (sloping up)
• Negative Correlation - trend of data points has a best line of fit that is negative (sloping down)
• No Correlation - trend of data points does not have a best line of fit

Step-by-step explanation:

According to the graph and the data set, we can see that we do indeed have a negative correlation trend. Therefore, options B and D can be eliminated.

Looking at the graph, we can see that we can definitely tell that it is a negative slope and it would be pretty steep. Therefore, the best answer choice would be A. Strong negative.
