This tutorial is based around responses to the National Student Survey. The raw data, originally from HEFCE is available as tab delimited file NSS_2014_FT.txt

There are around 50,000 objects of type NSS to be checked. Each object gives the details of the responses made to one question by the students studying one subject at one institution. For example - students studying "(8) Computer Science" at "Edinburgh Napier" gave the following responses to question 22 ("Overall, I am satisfied with the quality of the course"):

{institution:Edinburgh Napier University,question:22,subject:(8) Computer Science,score:93,response:146,sample:200,answered:[3,1,3,51,42]}
  • In all, 146 students answered that question in the survey
  • Exactly 200 students were eligible to take the survey
  • The score was 93% for that question (percentage mostly agree plus percentage definitely agree)
  • 3% definitely disagreed with the statement, 1% mostly disagreed, 3% were neutral, 51% mostly agreed and 42 definitely agreed
