Data Entry Error Affects More New York PPM Results
Last week, Arbitron said it would delay the New York PPM for one week after a data-entry error was discovered. On Tuesday, the company told subscribers that the error, manually entered population data, was transposed, and occurred during preparation for the October, 2008 report processing. Now it appears to have affected New York estimates from Holiday 2008 through March 2009.
"Please note that we are taking additional quality-control measures for future reports," Arbitron told subscribers in an e-mail. "These measures include the replacement of manual processes that rely on clerical data entry with automated processes where possible. We appreciate your patience and apologize for the inconvenience."
April's PPM number will be released on Wednesday, May 27 and the revised data for Holiday, 2008 through March, 2009 will be released June 8.
