The most efficient and powerful statistical techniques are of little value unless application is possible within the resources of the statistical worker and, since statisticial data are highly perishable in nature, unless the analysis can be accomplished in a minimum of time. A major obstacle to the use of important techniques available to the statistician often is the cost and time involved in the calculations necessary to complete the analysis. Many of these calculations can be simplified directly without computation. There are innumerable tables that are of values for such uses.
