Abstract:

Sample scaling apparently can be responsible for a considerable reduction in the total cost of conducting a timber sale. This saving is, of course, offset by differences between total sale value as estimated from the sample and the total value that would result from scaling all logs. Such differences will tend to favor neither the buyer nor the seller if reasonable care is taken in selecting the sample. However, there is always a chance, as in any sampling venture, that a large difference will occur. This chance can be made acceptably small by increasing sample size and by using the most efficient sampling method. A sampling method which involves weighing all loads of logs was found to be more costly for equal precision than another method which requires sample sealing only and no weighing. However, the method which requires weighing would perhaps be more efficient whenever load weights are inexpensive and whenever load weights vary considerably.
