UK DATA ARCHIVE DOCUMENTATION

3652 International Passenger Survey 1995


Data Archive processing standards
---------------------------------
The data were processed to the UK Data Archive's 'B' standard. A 
substantial series of checks was carried out to ensure the quality of 
the data and documentation. Firstly, checks were made that the number of 
cases and variables matched the depositor's records. Secondly, logical 
checks were performed on a sample of 30 +10% of the remaining nominal 
(categorical) variables had values within the range defined (either by 
value labels or in the depositor's documentation). Thirdly, any data or 
documentation that breached confidentiality rules were altered or 
suppressed to preserve anonymity.

All notable and/or outstanding problems discovered are detailed under 
the Data and documentation problems heading below.
