5.3 The following sample data were collected by the owner of a private 640-acre forest reserve. He did a sample of 10 acres as a trial survey for the entire reserve. He needs to set up and test a computer file system using SPSS’s Data Editor. The 10-acre sample was subdivided into 2.5 parcels, with each yielding the following data: hardwood trees, softwood trees, new-tree growth, stage of decay for fallen trees, soil moisture content, and crowded conditions. Your database will have four cases (4 × 2.5 = 10) and seven variables. Enter some fictitious data for the newly created variables on the four 2.5-acre plots.
