In “Evaluating Salary Survey Methodologies,” Senior Researcher Jonas Johnson, Ph.D., examines the methodologies behind three sources of salary survey data: surveys from national statistics offices, traditional salary surveys, and salary survey analytics.

“While compensation researchers genuinely work to provide accurate information,” writes Johnson in the report, “there remain inherent strengths and weaknesses to different methods of collecting, interpreting, and reporting data.”

Johnson discusses the pros and cons of each salary data source to help compensation professionals decide which source is right for their needs. Statistical topics covered include level of analysis limitations, range restriction, and regression to the mean.
