COVID19 Cases #2 – Is the UK an outlier internationally?

January 9, 2021 By Nigel

An unfortunate side effect of COVID19 has been ugly political debates over the best way to tackle the pandemic.  Often politicians will claim because country X does this, the UK should be doing it as well.  I decided it was time to do a proper comparison of the UK with other countries to see what extent the UK is an outlier and whether there are some countries we should be using as templates.

Pay Gaps #19 – Employers should report their Ethnicity Pay Fingerprints

November 29, 2020 By Nigel

The UK government has promised to give their views and proposals for introducing Ethnicity Pay Gap (EPG) reporting by the end of 2020.  A year ago, I pointed out statistical, data & ethical issues with EPG and listed 5 possible ways EPG could be introduced but I have not yet focused on what employers should be reporting.  I have now concluded that Ethnicity Pay Fingerprints are vastly superior to Ethnicity Pay Gaps and my new recommendation is that all employers with 500 or more employees should be required to report their Ethnicity Pay Fingerprint (EPF) instead of their Ethnicity Pay Gap.  If EPF is widely adopted and found to be beneficial then I would recommend that reporting of other protected characteristics such as gender & disability should be reported using Pay Fingerprints instead of Pay Gaps.

Data Driven Decision Making #1 – New Statistical Guidance for Land Contamination Surveys

October 11, 2020 By Nigel

On 30th September 2020, CL:AIRE (the industry body for the land contamination & remediation sector) published new professional guidance for “Comparing Soil Contamination Data with a Critical Concentration“.  The 46-page document advises how to use statistics when assessing land contamination and whether it is safe for development.  I was the lead author of the guidance and I spent 4 years working with CL:AIRE’s steering committee on what the guidance should cover.  The 4 years were bookended by two statements published by the ASA (American Statistical Association) on the use & misuse of P-Values in 2016 & 2019 and in writing this guidance I felt was I an ambassador for turning those statements into something that could used by non-statisticians to make real life decisions that have an impact on us all.

COVID19 Cases #1 – Latest Data and Trends for England

September 27, 2020 By Nigel

Last updated on 27th September 2020 but downloadable spreadsheet in section 3a was updated on 19th October 2020.  I will update the post when I get the time!

The latest data for COVID19 (Coronavirus) cases in England as of Saturday 26th September 2020 shows the number of people testing positive for COVID19 is up 60% from a week ago but this masks extreme regional disparities that make the national trend meaningless.  The North is in the grip of a second wave unlike the South which is not.  Unless recent trends in the North abate, the scenario of 50k positive tests per day by the end of October recently postulated by the Chief Scientific Officer remains feasible.
