My healthcare profession focuses on biostatistics. Biostatistics is a scientific branch of statistics, which constitutes a fundamental discipline of public health. It focuses on the development and application of statistical techniques and methods to analyzed data in order to extract the necessary information. His area of ​​interest is not limited to biological sciences, research work covers medicine, pharmacy, public health and agriculture. [Wikipedia] As an integral part of public health, biostatistics is responsible for understanding a health event to design experiments, collect data for the experiments, understand the collected data, and make inferences and interpretations based on the results analyzed. The interpretations could be used to predict a health event, identify any health trends, and identify factors affecting the health event. [textbook]Biostatistics could be considered the fundamental science of assessment work in the public health textbook. Since public health is a science aimed at preventing disease and prolonging life at the population level [textbook], the ability to understand, collect, analyze and interpret data is extremely important. For example, when forecasting the epidemic of seasonal influenza, in addition to epidemiology work, work on analyzing the rule of the timing of the epidemic in history and monitoring the appearance of the number cases are all based on statistical techniques. [CDC article. ] Additionally, biostatistics techniques also apply to annual vital statistics, which require biostatisticians to monitor the number of people in the country. Since the database is very large and many types of data need to be considered, such as newborns, death cases as well as immigrant people, biostatist...... middle of paper . ..... your health professional role, what would you say? Understanding public health is important for future biostatistics work. First of all, since biostatistics is designed to solve problems in the field of health and medicine using statistical methods, we must have a clear idea of ​​the work of public health and therefore be able to design a good experience or a good model to solve problems and provide suggestions of interest in practice. In addition, we also need to understand the types of factors that most concern public health, such as risks to the health system, influencing factors in disease transmission, and polluted elements in the environment. Understanding this can help us develop a better data collection strategy. Finally, since public health works to solve health problems at the population level, it requires the ability to work on big data..
