In a small district there are 10 villages with a total of 160 farmers          who each have one field in which to grow rice. A census of the area has          been undertaken and the acreage cultivated by each farmer is known. There          is now to be a crop cuttin survey whose main aim is to estimate the mean          yield of rice per acre and hence the total production of rice in the district.          The survey will also be used to investigate the use of fertilisers and          the different varieties of rice used in the district.<\/p>\n<p>The resources available allow for 30 plots to be sampled. The plots to          be harvested are 1\/80 acre but the yields are recorded in bushels per          acre. Students use a multistage sampling scheme. For example:<\/p>\n<ol>\n<li>Select <em>x<\/em> villages<\/li>\n<li>From each village choose <em>y<\/em> fields<\/li>\n<li>Select <em>z<\/em> plots from each field<\/li>\n<\/ol>\n<p>The game consists of 10 boxes each containing a number of envelopes,          which themselves contain a number of slips of paper. The boxes represent          a village so students select the boxes corresponding to their chosen villages.          They open the boxes and select the envelopes labelled with their chosen          field number. Information on the size of the field, the variety of rice          used and the amount of fertiliser applied is also displayed on the envelope          label. Finally, they select the slip of paper labelled with their chosen          plot number and record the yield.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This game is a rice survey based on an actual survey carried out in Sri Lanka.
