Pay Gaps #17 – How to Spot an Incorrect Median Gender Pay Gap

August 11, 2020 By Nigel Marriott

I have a spotted an incorrect median gender pay gap published by a well known name in a certain industry. They shall remain nameless for now since I am trying to get them to accept their error and publish a new gender pay gap report on their website. I know they have made an error because their published data violates the laws of mathematics as I will explain in this blog. All it takes to spot such an error is a simple calculation you can do in your head and an understanding what the median measures.

Pay Gaps #16 – Eliminate your gender pay gap by playing Blackjack!

August 2, 2020 By Nigel Marriott

Imagine where you work, the median women earns 33% less than the median man. Although your workplace is gender balanced with 50:50 men:women, the pay gap exists because 1 in 4 of managers and 3 in 4 of the lowest paid admin staff are women. How long will it take for the pay gap to disappear assuming that all future recruitment at all levels have 50:50 candidate pools with men and women equally likely to be appointed to the role?

Pay Gap Trends #3 – Did the UK gender pay gap narrow in 2019?

June 14, 2020 By Nigel Marriott

On 24th March 2020, the UK government suspended enforcement of the gender pay gap reporting deadline of 5th April. As of today, just over 50% of employers have reported their 2019 gender pay gap figures. Despite this shortfall, I have used statistical imputation methods to calculate that the median gender pay gap narrowed in 2019 from 9.6 pence in the pound to 9.0-9.2 pence in the pound.

June 3, 2020 By Nigel Marriott

In April, I was asked to analyse the trends in UK gender pay gaps over the 3 years of mandatory reporting from 2017 to 2019 for Practical Law. They were interested in 7 customised sectors and the links to these can be found in this post.

Pay Gap Data #3 – Where can I find gender pay gap data for 2019?

June 2, 2020 By Nigel Marriott

This post was updated on 3rd June 2020 with the latest data

Update 5/4/20 – On 24th March, the government suspended enforcement of the deadline for reporting 2019 gender pay gaps due to the coronavirus outbreak. As of now, Only 40% of employers have reported their 2019 data. Employers are still required to report 2019 data but will not be punished for being late in doing so.

The government requires all organisations employing 250 or more employees to submit gender pay gap data. All data is available to the public and can be found on the government’s gender pay gap website. I have downloaded this data and created a spreadsheet tool to present the data in a more user-friendly and visual format.

The Coronavirus Pandemic is a worldwide challenge many of us will have not experienced before. It is natural to want to seek information on the risks and in our world today, it has never been easier to find data, analyses and opinions. Unfortunately, a lot of what you will read out there is either unhelpful or actively misleading. As an independent statistician with 30 years experience of explaining statistics to non-statisticians, my contribution to this crisis will be to try and sort the good from the bad hence this post.

Coronavirus #2 – What sample size does Boris need to lift all restrictions?

April 2, 2020 By Nigel Marriott

April Fools day 2020 saw the hive mind of social media asking what the sample size should be to measure the extent of the Coronavirus in the UK. I could see that many people responding were reaching for standard methodologies which are usually are based on specifying a desired confidence interval. In doing so, they were overlooking a much more effective and relevant alternative based on the methodology of Acceptance Sampling, first developed by the US Military in World War 2.

Pay Gaps #14 – Gender Pay Fingerprints are better than Gender Pay Gaps

February 19, 2020 By Nigel Marriott

Recently, a lot of people have been making incorrect claims about what a gender pay gap tells you. I have been pointing out these errors but in doing so, I am conscious I come across as a pedant or a negative voice. The problem is that the official gender pay gap measure (the difference between the median man and the median woman) is just a single number and that single number does not capture the full nuance of what is going on. I have decided it is time to introduce the Gender Pay Fingerprint to the world as an alternative and going forward, I will be encouraging people to use this instead.

Pay Gap Case Study #3- Will the BBC’s gender pay gap narrow after losing to Samira Ahmed?

February 13, 2020 By Nigel Marriott

The BBC presenter Samira Ahmed has won her claim for equal pay at the employment tribunal. She successfully claimed that Jeremy Vine was an appropriate comparator for her pay. She is not the only female presenter to make a claim with over 50 more claims under consideration at present. Assuming that these are all successful, will these have any effect on the BBC’s gender pay gap for 2019 of 7p in the pound?
