Sampling

__**SAMPLING**__

Random sampling is a method of selecting organisms for an experiment where every organism has an equal chance of being selected. This method is important in experiments of measuring productivity because it helps make more accurate generalizations.


 * Productivity of Grass Experiment:**
 * Random sampling is used to create an equal opportunity for every blade of grass in a specified area to be selected for use in the experiment
 * In this method, a small grid was placed down on the area every X number of steps. Grass was then clipped from within a certain square on the grid; the same square on the grid must be used each time.
 * This sampling method is important for this experiment because to get an accurate productivity estimate of an area, the sample must be random otherwise no generalization can be made.
