A grid is drawn over a map of the study area, Random number tables are used to obtain coordinates/grid references for the points, Sampling takes place as feasibly close to these points as possible, Pairs of coordinates or grid references are obtained using random number tables, and marked on a map of the study area, These are joined to form lines to be sampled, Random number tables generate coordinates or grid references which are used to mark the bottom left (south west) corner of quadrats or grid squares to be sampled, Can be used with large sample populations, Can lead to poor representation of the overall parent population or area if large areas are not hit by the random numbers generated. To do this some basic maths is required (total number of protestant (or catholic) streets/total number of streets x sample size).
