Because in certain years such as 2001 the data points are not integers (3.5)

The average cannot be an integer as well. For this they use \(\approx\)

In 2003, the actual unemployment rate is 8.5% and it is incorrect, If it were 6% instead.
Average unemployment rate for the 10years will be (8.5-6)/10= 2.5/10=0.25
