What do we do with the data?
Much of the Scottish data is published as ‘cumulative totals’. This gives the current total so to get a daily or weekly figure we subtract the previous value from the current.
The daily data is very variable. The list below is a snapshot of 7 days worth of numbers of daily tests reported. On a graph this variation would swamp any trend in the overall data. For that reason, all daily data is averaged over the 7 days (that day and the 6 previous.). In this case, the data point for the last day would be shown as the average value of 18,930.
It should be noted that this variation is absolutely to be expected for data being collected daily like this – it is not a sign of a problem.
How do you compare the number of cases in the Western Isles NHS area with those in the Glasgow NHS area or with UK or global statistics?
I am adopting the method used elsewhere which is to quote figures per 100,000 of population.
To calculate this we divide the data by the population/100,000
The Scottish Government use the figure of 5,463,300 for the population of Scotland.
If the number of cases was 1000 we would divide that by 5,463,300 /100,00 which is 54.633
1000/54.633 = 18.3 per 100,000
The populations of each health board area as published by the Scottish Government are
|NHS Ayrshire and Arran||369360|
|NHS Dumfries and Galloway||148860|
|NHS Forth Valley||306640|
|NHS Western Isles||26720|
|NHS Greater Glasgow and Clyde||1183120|
