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

April 24, 2019 By Nigel

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:-

  1. Unilever UK Ltd
  2. Unilever UK Central Resources Ltd

Clicking on those links will take you to the government’s gender pay gap website where you can see their published figures.  For this post, I will be using my own spreadsheet which you can download for yourselves here.

Stats Training Materials – Forecasting & Risk Modelling

March 1, 2019 By Nigel

All organisations want to understand what has happened in the past and what will happen in the future.  The use of statistics and statistical thinking is essential to be a better forecaster but that doesn’t mean it is easy to do!  At the same time, we are bombarded with forecasts in the media and that can make it difficult to decide which forecasts to pay attention to and which can be ignored.

My course “Identifying Trends & Making Forecasts” is all about doing the basics right when it comes to analysing trends and making predictions.  To support this course, this post makes available a variety of material in the public domain covering the following themes:-
