Y1 - 2020 N1 - T2 - Foundations of Clinical Research: Applications to Evidence-Based Practice, 4e AB - In the investigation of most clinical research questions, some form of quantitative data will be collected. Initially these data exist in raw form, which means that they are nothing more than a compilation of numbers representing empirical observations from a group of individuals. For these data to be useful as measures of group performance, they must be organized, summarized, and analyzed, so that their meaning can be communicated. These are the functions of the branch of mathematics called statistics. SN - PB - F. A. Davis Company CY - New York, NY Y2 - 2024/03/28 UR - fadavispt.mhmedical.com/content.aspx?aid=1187148990 ER -
