All data is confidential. Every effort is made to ensure that the salary tables protect the confidentiality of contributor data and are statistically meaningful. A minimum number of cases (five) are assigned for each position. Some positions have been omitted because of the small sample size. Where the number of cases recorded equals the minimum, publishing is restricted to the median and average values only. The CBR is only available to those that supply data thus enhancing the resource's integrity and credibility. All data released is fully compliant with the Federal Trade Commission's Anti-Trust Act provisions for salary surveys.
