Abstract
Many physicians in clinical practice have not had formal training in statistics, but a basic knowledge of certain aspects of statistics is essential for the physician densitometrist. Quality control procedures for the various machines require some statistical analyses. The computer-generated reports of bone density data include statistical devices, such as T- and z-scores and confidence intervals. In order to interpret serial studies, the physician must understand the concept of precision, and be able to calculate the precision of repeat measurements in his or her facility. These concepts and others are discussed in this chapter.
