Figure 12
A histogram with approximately 20 vertical bars representing the posterior mean distribution of differences in means post-2014 against the previous decade. The x-axis is labeled ‘Difference in Means (Post - Pre)' and ranges from 0.0 to 1.2. The y-axis is labeled ‘Density' and ranges from 0.0 to 3.0. The histogram shows a distribution with a peak around 0.47, indicated by a red dashed line labeled ‘Mean: 0.47'. The 2.5 percentage quantile is marked at 0.15 with a blue dashed line labeled ‘2.5 percentage: 0.15', and the 97.5 percentage quantile is marked at 0.77 with another blue dashed line labeled ‘97.5 percentage: 0.77'. The distribution appears to be slightly skewed to the right. All values are approximated.Posterior mean distribution (1,000 samples): post-2014 against previous decade
