We expect our graduates to be highly competitive in three primary settings: This training is conducted in the innovative and interdisciplinary public health culture of the College of Public Health and Health Professions and the College of Medicine. Outcomes may also be described with more than two categories. the scale of measurement—the precision with which a characteristic is measured—also determines the statistical methods for analyzing the data. the observations are said to be measured on an ordinal scale. in Presenting Problem 5 Ballard and colleagues (1998) use the following nominal characteristic to describe the outcome in infants being treated with antenatal TRH: the development of respiratory distress syndrome.

Many of the discussions are based on applications of statistical methods in the design and analysis of dose response studies. These following courses are designed to give clinicians in the UF Health Science Center an opportunity to learn more about the application of statistical methods. Intro level statistics (PHP 2507/2508 or PHP 2510/2511) recommended. The risk ratio using person-years of observation is The risk ratio for person-years is similar in size to the value based on subjects because both the aspirin and control groups were observed for similar periods of time. c.
