Pay Gaps #9 – How to close your gender pay gap with DMAIC

July 5, 2019 By Nigel Marriott

So you’ve measured your gender pay gap (correctly I hope!) but you don’t know what to do next?

You are not alone, many employers are still getting their heads around how to interpret their pay gaps and are struggling to work out what it means for them. One outcome is that many consultants are out there waiting to advise you and among them are statisticians like me. But what exactly is it that statisticians bring to the party compared to other consultants? One answer is that statisticians use DMAIC to help organisations improve the quality of their products, services and processes.

June 8, 2019 By Nigel Marriott

On June 5th 2019, I had the privilege of being able to talk to the Treasury Select Committee about the “Effectiveness of Gender Pay Gap Reporting“.

Pay Gap Case Study #2 – Year on year trends, the good, bad and Unilever

April 24, 2019 By Nigel Marriott

Welcome to my next case study where I look at the pay gap figures of Unilever Ltd. Unilever turn out to be a very interesting case study for analysing year on year changes in their published statistics. In this case I will be looking at the changes between 2017 and 2018 for the two Unilever business units that have submitted GPG data which are:-

Pay Gaps #3 – 12 ways to improve public confidence in gender pay gap data

June 27, 2018 By Nigel Marriott

This is intended to be a briefing note for anyone interested in seeing gender pay gap data being used properly. Gender pay gap data is now part is the business and political discourse in the UK and is likely to be so for some time. If the goal of gender pay gap reporting is to remove disparities in pay between men and women, then it is essential that the public has confidence in both the quality of the data being published and the correctness of any interpretations of the results. With the first round of data reporting out of the way, it is time to learn lessons, identify improvements and see that these are implemented. Following extensive analysis of the 2017 round of results, I have identified 12 ways to improve the quality of the data being reported and make interpretations of the results more meaningful.

Pay Gap Case Study #1 – Life on Mars

May 21, 2018 By Nigel Marriott

The UK is facing the challenge of interpreting the first round of gender pay gap data. I listed some of the challenges in my article “the 7 ways to misuse gender pay gap data“ where in statement 4, I concluded a lack of understanding of the laws of chance will result in unjustified allegations of gender discrimination against some organisations. In this article, I want to demonstrate the laws of chance using nothing more than some dice and coins, a process known as simulation. My simulation model is simple enough for you to repeat by yourselves and at the end, you will have a better idea of the extent to which median gender pay gaps can vary even when organisations do not discriminate in any shape or form.

Pay Gaps #2 – 1 in 10 organisations have published incorrect gender pay gap data. Are you one of them?

May 12, 2018 By Nigel Marriott

The first round of gender pay gap data is now available for all organisations employing more than 250 employees. The UK now faces the challenge of interpreting this data and using it properly which will not be easy given “the 7 ways to misuse gender pay gap data” I recently wrote about. In the short term, there is an immediate need to resolve errors in the data published and I will demonstrate that potentially 10-15% of organisations have entered incorrect data into the government’s database.

Pay Gaps #1 – 7 ways to misuse gender pay gap data

May 11, 2018 By Nigel Marriott

April 2018 was the deadline for submitting gender pay gap results and we now have the first detailed picture of how pay differs between men and women in the UK. A nifty government website can be used to look up pay gap details for any company employing more than 250 employees and you can also download the results for further analysis. So what will happen next? Will the data be used properly to inform debate about how men and women are paid or will it be misused for personal and political gain?

I believe this data can be of benefit to the debate around gender equality but my fear is that to begin with, it will be misused, misinterpreted and reinforce the saying “lies, damned lies and statistics”. So if you want to misuse gender pay gap data, who better to ask that a professional statistician like me who will show you how you can do this by commenting on 7 plausible statements.
