=== Interactive editing ===

The term interactive editing is commonly used for modern computer-assisted manual editing. Most interactive data editing tools applied at National Statistical Institutes (NSIs) allow one to check the specified editsduringedits during or after data entry, and if necessary to correct erroneous data immediatedlyimmediately. Several approaches can be followed to correct erroneous data:

*Recontact the respondent

*Compare the respondent's data to his data from previous year

*Compare the respondent's data to data from similar respondents

*Use the subject matter knowledge of the human editor

Interactive editing is a standard way to edit data. It can be used to edit both [[categorical]] and [[continuous]] data.<ref>Waal, Ton de et al. "Handbook of Statistical Data Editing and Imputation".

In selective editing, data is split into two streams:

*The critical stream

*The non-critical stream
