A class created a scatterplot by looking at the predicted temperature vs. the actual temperature for their city for 30 days. The result formed a strong positive correlation, with the exception of one outlier. Which would most likely cause the outlier?

• A moderate predicted temperature and a very high actual temperature

• A moderate actual temperature and a moderate predicted temperature

• A very high predicted temperature and a very high actual temperature

• A low actual temperature and a low predicted temperature
