Calculate and interpret the correlation coefficient : The correlation coefficient tells us how close the data is to resembling a straight line on a scatterplot. The correlation coefficient ranges from −1 to −1. A coefficient of 1 or −1 means that the data is a straight line (there is a perfect linear relationship between the two variables), while a coefficient of 0 means that the data do not resemble a straight line (no linear relationship between the two variables). Note: The coefficient you get will be slightly different because this temperature data is the station data, not the combined air-surface temperature data.
