Examples - Unusual Points

Looking at the residuals graph there is only one point that is more than 1.1 million square kilometres away from the trend. This occurred in September 2007 and may have been due to an unusually hot summer.

Absolute Highest Value: 8700

Absolute Lowest Value: 6700

Looking at the residuals graph due to the inconsistency of the data there are a large number of residuals between 2007 and 2010 that are outside the acceptable range. This is during the financial boom so it may be due to people being more willing to have children and therefore not worrying about the timing so much, therefore the normal patterns do not happen.

Absolute Highest Value: 1100

Absolute Lowest Value: 100

Looking at the residuals graph we can see that there is only one point where the residuals exceed the 10% level. This occurs around March/April 2003
