As with last Friday, I'm going to do a statistical comparison on the proportion of deaths in both Scotland and England, and the estimated 'R' rate in both areas, to determine whether the approach being taken by Scotland is suitable compared to the evidence that Sturgeon explains is 'justifying a more cautious approach' to exiting lockdown.
Daily Deaths
First it is important to note the relative populations of both Scotland and England:
Scotland: 5.454 Million
England: 55.98 Million
We can see here that the English population is approximately equal to 10 times the Scottish population, so in order to justify a slower and more cautious approach to exiting lockdown, one would expect the Scottish daily deaths multiplied by 10 to be greater than the English deaths. Let's compare figures from yesterday:
18th June 2020:
Scotland: 2 Deaths
England: 62 Deaths
Evidence suggests pandemic is approximately 3.10 times more prominent in England than in Scotland
17th June 2020:
Scotland: 9 Deaths
England: 77 Deaths
Evidence suggests pandemic is approximately 1.17 times more prominent in Scotland than in England.
16th June 2020:
Scotland: 5 Deaths
England: 79 Deaths
Evidence suggests pandemic is approximately 1.58 times more prominent in England than in Scotland.
15th June 2020:
Scotland: 0 Deaths
England: 28 Deaths
Evidence suggests pandemic is significantly more prominent in England than in Scotland.
On average (calculating the mean), the pandemic is approximately 1.755 times more prominent in England than in Scotland (taken from the data through 16th - 18th June). This means that Scotland should, in theory, be able to exit lockdown more quickly than in England as the presence of the virus is proportionally smaller than it is in England. In reality, the opposite is happening and Sturgeon is insisting on exiting lockdown more slowly because the situation in Scotland is more dangerous than in England (or so she claims). I'm afraid I don't draw the same conclusion from looking at the evidence.
Comparing 'R' number estimations for both Scotland and England:
Scotland: 0.6 - 0.8
England: 0.8 - 1.0
This suggests the same as the death rate, that the pandemic is less prominent in Scotland and that a faster and less cautious approach to relaxing restrictions could be taken in Scotland compared to England. In reality, the opposite is happening, Sturgeon insists on taking a more cautious approach as she states 'The evidence suggests the 'R' rate may be higher in Scotland than in the rest of the UK'. Once again I do not reach the same conclusion and I am unsure how studying the evidence is leading her to draw the conclusions that she is reaching.
