Abstract
The objectivity (interexaminer reliability) of measurement in chiropractic provides a basis for judging the quality of information in clinical research and practice. Objectivity may be determined by formal measurement evaluation studies and by sampling within clinical trials. Interpretation of inter-examiner reliability requires descriptive and inferential statistics selected on the basis of the mathematical properties of data, appreciation of the clinical meaning of a particular measure, and recognition of the role of chance. Methods of data analysis include scatter-plots, contingency tables, time-series graphs, and correlational and concordance coefficients. Many kinds of objectivity evaluations are well within the capacities of private practitioners and student clinicians.
