In this assignment you will use statistical tests for non-normal data. You may usemethods (non-parametric statistics tests) and tools (R, Excel, or SPSS) of your ownchoice - please don't rely on one tool or method, variety is expected. It is notnecessary to replicate any test you carry out, ie if you perform a test inR it is notnecessary to repeat in SPSS and/or Excel. A data file (from the 2011 Census ofIreland) is suggested, though students are permitted to choose a different file ifthey wish (subject to approval by Dr O'Loughlin). Your task is to prepare astatistical report based on the data in the file.UPDATE LINK:The Central Statistics Office provides data on "Small Area Population Statistics" –see:http://airo.maynoothuniversity.ie/files/dDATASTORE/small_areas/theme_11_small_areas.csvThis CSV file has 18,488 records based on 68 columns of data. You are notexpected to use all the data in the file and you may reduce to eliminate unuseddata if you wish.
