This article provides the reader with guidance on the effective selection and use of wage and salary surveys to assure the availability of accurate data to which the firm's rates of pay can be compared. This paper has concentrated on the need for and method of careful selection of survey data, with the intent of assuring the greatest possible degree of comparability and accuracy in the data, prior to statistical analysis. The method of selection is important because even the most careful analysis of bad data produces only more bad data.
