Final executive report
The final report unifies all three millstones/sections which you have completed which
showcases all the statistical techniques you have learnt to date. This report is a final take on
this problem and should include the key results that you wish the Board to learn about this
puzzling phenomenon in the labour market. Your report will consist of five core sections:
• Introduction and executive summary (1/2 page max for executive summary).
• Section 1 (using Milestone 1) which comprises a summary of key features of data based
on your first milestone and any feedback received.
• Section 2 (using Milestone 2) comprises a summary of statistical tests conducted based on
your second milestone and any feedback received.
• Section 3 (using Milestone 3) will investigate the productivity story in the claims above.
• Concluding remarks.
Please note that Section 1 and Section 2 is not a copy/paste of all your reports for the first two
milestones. These sections should report the take home messages from your detailed analysis
that you have completed. No need to re-report the tables and graphs from those milestones.
You should summarize the key points and state briefly the statistical evidence/argument that
support those key points.
Your report should tell a story that uses all the key conclusions you have come to from the first
two milestones, and which will probably also inform your analysis for the last milestone.
