From the question we are informed about how a marketing researcher subcontracts the data collection process to a field services firm. After the data is collected, the researcher is editing the questionnaires, and finds a large number of mistakes. In many cases skip patterns were not followed, and difficult questions were often skipped. The researcher contacts several of the persons that did the interviewing and finds that they received little, and in some cases, no training or supervision.
