UK DATA ARCHIVE DOCUMENTATION 4620 - British Election Panel Study, 2001; Waves 1 and 2 Data Archive processing standards --------------------------------- The data were processed to the UK Data Archive's 'A' standard. A rigorous and comprehensive series of checks was carried out to ensure the quality of the data and documentation. The most important procedures were as follows. Firstly, checks were made that the number of cases and variables matched the depositor's records. Secondly, checks were made that all variables had variable labels and all nominal (categorical) variables had value labels. Where possible, either with reference to the documentation and/or in communication with the depositor, absent labels were created. Thirdly, logical checks were performed to ensure that nominal (categorical) variables had values within the range defined (either by value labels or in the depositor's documentation). Lastly, 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. Conversion of data and documentation formats -------------------------------------------- The documentation refers to data file as prepost.*** prepostagg.*** (file based on the original but also containing constituency-level information for aggregate analysis) replaces this file.
