2014

Explanation:

Standard deviation is a statistical concept that aims to explain the dispersion of the data in relation to the expected value (mean). Thus, the higher the standard deviation, the more dispersed the data will be in relation to the mean. Therefore, if in 2013 the standard deviation was 3.96 and in 2014 the standard deviation was 4.08, this means that in 2013 the data points tend to be closer to the average or expected value than in 2014. Thus, in 2014 the random distribution is more dispersed.
