A contradictory data record

A fieldwork team receives a file containing age, work history, income and service-use answers. One record gives age seventeen and twenty-five years of paid work experience. Another gives age two hundred and fifty. A third records income as zero, but the paper questionnaire shows that the respondent refused to answer. The team has access to the original forms and a documented recontact process. Its manager wants a clean file by the afternoon but has not authorized replacing unusual values with the sample mean. The analyst must classify the three problems, use evidence to correct them where possible and preserve enough information for a later reviewer to understand what was done.
