        • Random – any                                                  • Multi-stage – large


           member of population                                             population, broken


           has equal chance of                                              down into smaller


           being chosen                                                     chunks, sample


        • Systematic – random                                               chosen at random


           initial number then                                              from chunk


           regular number after                                         • Cluster – as above



        • Stratified – population                                           but all of small chunk

           is ‘grouped’ and sample                                          is sample


           randomly chosen
                                                                        • Quota – known
