The following are explanations of key components of the graphical results charts reported for either Qwest's regional or state-specific performance results:

• Column headings for data tables accompanying graphs:
  • Date: Reporting month of data
  • CLEC Num. or Numerator: The quantity meeting the criteria described in the performance indicator definition for the numerator of the formula for the measurement, dealing with services Qwest provides to CLEC(s).
  • CLEC Denom. or Denominator: The sample size or number of events contributing to the measurement, as defined in the PID for the denominator in the formula, dealing with services Qwest provides to CLEC(s).
  • CLEC Result or Result: The outcome of executing the formula calculation defined in the PID to represent the specified dimension of service performance provided to CLEC(s).
  • Std. Dev.: The standard statistical parameter representing the degree of variability of performance in the PID-specified dimension of the service (e.g., installation or repair) for the events measured in accordance with the PID. Standard deviations are generally reported where statistical methods will be used to evaluate the comparisons between performance for CLECs and for retail.
  • Qwest Num.: The quantity meeting the criteria described in the performance indicator definition (PID) for the numerator of the formula for the measurement, dealing with services Qwest provides to retail customers or, as specified, to "itself" (e.g., for network components used in providing retail service, as stated in the PID).
  • Qwest Denom.: The sample size or number of events contributing to the measurement, as defined in the PID for the denominator in the formula, dealing with services Qwest provides to retail customers or, as specified, to "itself" (e.g., for network components used in providing retail service, as stated in the PID).
  • Qwest Result: The outcome of executing the formula calculation defined in the PID to represent the specified dimension of service performance provided to retail customers.
  • Z-Score: This is either a modified z-score, based on the ILEC variance, for the difference between CLEC and retail results reported in the table, calculated using standard statistical methods, or, if a permutation or exact proportions test is run on the data, it is the z-score equivalent of the calculated p-value for the statistical test.
  • Parity Score: A numeric indication of whether the reported difference in results is statistically significant, based on the z-score and a critical value. Often, the critical value is 1.645, but in certain instances a different critical value is used, as specified in the PAP for a particular state. A positive Parity Score means the result is statistically significant and, if the critical value is 1.645, statistically significant at the 95 percent confidence level. A negative Parity Score means the result is not statistically significant at the 95 percent confidence level, if the appropriate critical value is 1.645.
  • Met/Miss: The met/miss column reflects as ‘yes’ if the applicable standard for the PID/sub-measurement combination is MET for the month according to the CPAP criterion. The column will reflect as ‘no’ if the applicable standard for the PID/sub-measurement is MISSED for the month.
• Response Time: In the PO-1 measurement, where pre-order query/response transaction time intervals are measured, the response time column reports the time interval associated with the transaction specified in the heading of the table.
• Each graph depicts values from the "result" columns in the table at its left, with the reporting months shown along the bottom or "x" axis and the value scale along the left edge or "y" axis.
• Where there is no retail comparison reported, the graph only reports the result representing the service performance as provided to CLEC(s).
• Where a benchmark applies, the graph shows a dashed line representing the benchmark that applies.
• Blank spaces in the table mean that there was no activity to be reported under the specified measurement in the reporting month.
• "N/A," or "not applicable," indicates that the statistical parameter is not defined, usually due to a divide-by-zero situation.
• Where no table or graph is provided for a measurement defined in the PID, there was either (1) no activity in any of the reporting months shown in the report for that measurement or (2) the measurement is under development, as of the date of the report.
