## Methodology - Unemployment Rate
The average unemployment rate is 9.8% with a standard deviation of 7.3%. The lowest rate is 0.4% (Uzbekistan)
while the highest one is 39.3% (Lesotho).
### For countries __above__ the mean the points for the score-bar are calculated as follows:
With the calculated mean and standard deviation an assumed normal distribution has been calculated. The
probability of a value equals the minus-points, i.e. a probability of 67% equals 33 points (100 - 67). ### For countries
__below__ the mean the points for the score-bar are calculated as follows:
As an unemployment rate of 0% reflects the absolute minimum this value should be 100 points. The average
unemployment rate should equal 50 points. This means that for every 0.2% unemployment rate a minus-point is given.
This method has been chosen as otherwise a country with 0% unemployment rate would just get about 91 points when
applying the assumed normal distribution method. This would not reflect the good performance of the country in
that area. ### Source
