The first step in error detection is to: reject an error value when it is very large or very small for a particular scaled item on the questionnaire. determine whether the software used for data entry performs "error edit routines" that identify the wrong type of data. categorize the number of errors to two or more questions, thus showing the relationship between those two variables. determine the amount of nonresponse to individual questions. identify the number of respondents who did not answer various questions on the questionnaire.
