Abstract
1. Cereal plots were sampled by three different methods; two systematic, and one involving a random location of sampling units. 2. The disadvantages of the systematic methods as compared with random sampling, emerged clearly. 3. These disadvantages were further emphasised in an analysis of earlier data on sampling methods. For this purpose the methods and. results of certain recent contributions to statistical theory were used. 4. By the use of a random sampling method, the variance due to sampling errors may be made a satisfactorily small fraction of the total variance of cereal plots one-fortieth of an acre in area.Keywords
