I am delighted to hear, via the Oxford alumni magazine Inspires, that PPEists are soon going to have more statistics built into their syllabus. This is a result of the university being selected as one of 15 participants in the Q-Step programme to encourage statistical literacy in the social sciences.
Being able to use and understand statistical methods is essential in the making and analysis of public policy. Social science only has one laboratory, and statistics is its only instrument. I benefitted hugely from a stats course provided in alongside the PPE course during my time in Oxford. I have since topped this up through Coursera and EdX.
